Let’s talk about night operations. This is a topic that often comes up, particularly with regards to modern night vision equipment. There was a string of comments about this in my recent post ‘Out In the woods’, which took on the form of a mini forum. There are multiple aspects to discuss about night operations, so my intent will be to give a broad brush of the various aspects in order to clarify, and then open it up to comment and discussion.
This blog is primarily concerned with the armed civilian in an SHTF environment. Thus, you will only have the equipment that you purchased or acquired. We can certainly take pointers from practices within the military, and that is part of the intent of this article, but we must also be realistic and realize that we are not going to be issued all the latest gear. The gear you have is often a function of what you can afford.
There is absolutely no reason why you cannot conduct effective night operations in a low tech manner. The flipside to this is if your enemy is equipped with high tech night vision equipment, then you may put yourselves at a disadvantage. So today I’m going to look at both low-tech and high-tech options. Remember, just because you have all the gear (and no idea), doesn’t mean you have it squared away. You can have a PVS 14 stuck to your eyeball, and a thermal imager in your pocket, but if you’re tactical moron blundering around the bush, then it really can’t help you. You can’t simply buy yourself safety!
‘Back in the day’ (like, the 90’s!) we used to patrol either without, or with minimal, night vision equipment. I have spent many an hour, or night, wandering around in the darkness either on training exercises or actual operations. It is entirely doable. The problem you may have is that when you are dealing with the challenges of operating in darkness, and someone else with night vision equipment is observing you do that, they have a clear advantage over you. Yes, we are not going to panic over the ‘all seeing eye of Mordor’ but have no doubt of the effectiveness of surveillance equipment when observing terrain at night. As your patrol moves in single file across the open hillside, cloaked in darkness, the OP a couple of miles away equipped with thermal surveillance equipment, will be watching you clear as day.
So let’s first look at some factors and considerations for operating at night without modern night vision equipment. Darkness is certainly a challenge: if you walk out of your brightly lit house into your backyard at night, it is hard to imagine operating in such darkness. However, natural night vision is a wonderful thing. It takes time to develop, anything from 45 minutes and improving over a couple of hours, and it can be lost in an instant of exposure to white light. On anything but a moonless, cloudy, and miserable night there is always light to see by. How much depends on the moon state and cloud cover; in fact just the other day out in the woods at my training site a half moon and clear sky was casting the shadows of the trees across the white snowy ground.
Natural night vision is something that you must develop and prize. As darkness falls you must allow the night vision to develop, without exposing it to white light. If you are planning on exposing yourself to light, such as flashlights, GPS screens and similar, then carefully guard the night vision in one eye by always keeping it closed when performing such tasks. The other thing about my vision is that due to the distribution of the rods and cones on the back of your eyeball, in darkness you will see better by looking slightly away from an object; your peripheral vision is better at night. Therefore, if you think you see something, resist the temptation of staring intently at it. This will actually mean that you see the object less clearly. Look slightly away from the object and you will get a better picture.
So, whether you are out in the woods in a patrol base, or in a building, as night falls you need to carefully guard your night vision. Consider, if you are based at a retreat location, only using low level red or green lights inside at night. Then, when you do go out on patrol you will find that you can actually see very well. You just need to gain the confidence, which will only come by practice, of walking around at night. I will add as an aside however, that the more exhausted you become the more you will tend to hallucinate at night. It is entirely possible to see things at night in the darkness that are simply not there, particularly if fear is playing on your mind. Be careful of this, and remain calm.
If you are operating low-tech, or perhaps you only have a couple of night vision devices to spread around, then this will have an effect on your patrol signals and formations at night. You will need to close up the distances, the spacing, between individuals in your patrol. At halts you will need to close up, usually into a herringbone formation (facing out alternately left and right), so each man touches the next man. This will not only aid with accountability, but if it is so dark that hand signals cannot be seen, you may have to pass signals by whispering into the next man’s ear. Bearing in mind that you may be observed by an enemy who is equipped with night vision devices, you don’t want to close up too much. Try to remain as spread out as you can while maintaining visibility with the patrol member in front of you. One of the great dangers when moving at night is splitting the patrol, and it is every man’s responsibility to ensure he does not lose either the man in front, or the man behind. Little techniques will aid with this, such as the use of glowing ‘Ranger eyes’ on the back of the cap, helmet, or equipment of the man in front.
Do not assume that darkness will mask your movement. At night you need to patrol as if it were daylight. The use of terrain, vegetation, and even weather masking, will help conceal your movement from those potentially observing you. Be wary of sky-lining yourself on ridges, silhouetting yourself, whether by following along the crest or by crossing over. Crawl over, breaking up shape using cover, if necessary. When using terrain masking, be careful: don’t simply follow the bottom of a ravine or defile. That will put you in ambush country. Better to contour somewhere between the bottom of the valley/draw and the ridge line: this will make your movement less obvious and also potentially place you in an awkward position for anyone that has set an ambush: you may either walk into the side/flank of the ambush, or just simply be further away than where they intended the killing area to be (i.e. the valley floor). It goes without saying that you should not use trails, even if they are easier to move along at night.
So there are challenges of moving at night when working low-tech. But it’s actually something that you can get used to after a little bit of practice. You can get very comfortable at it. You need to just take account of the difficulties the darkness presents, with the lower visibility, and compensate your patrol conduct as required. Your pace will be slower, in order to avoid excessive noise by blundering around in the trees. You will need to close up a little to take account of the reduced visibility. You’ll need to make extra efforts to ensure the patrol does not become split or separated. You will need to close up at halts in order to pass any hand signals, whispered messages, and to ensure accountability.
What happens if it goes hot? If you get into contact? Well, it’s really not that complicated. If it’s dark and you walk into a contact, then perform your contact drill as rehearsed, and fire at the enemy’s muzzle flashes. Remember that if tracer is involved, either by the enemy or by yourself, then it lights up at 100 meters from the muzzle (if the subdued NATO standard type). So it does not truly point both ways, which is why is designed to light up at 100 meters. If the contact is taking place at ranges greater than 100 meters then you can also use tracer as a means of target indication.
Consider the use of white light. If you are without night vision devices, then you definitely want to consider the use of parachute illumination rocket flares. Either the self-contained ones that come in a tube, or the ones fired from a flare gun. If you put up a parachute flare you can get anywhere between 30 to 60 seconds of illumination. It will move with the wind, and cause moving shadows on the ground. Note: if you are patrolling and one of these suddenly wooshes up, you should have time to hit the ground before it pops and illuminates the area. If you are caught by one actually bursting then it is often better to sink to the ground slowly with the moving shadows, rather than trying to bomb burst into cover. This is a different immediate action from that with the trip flare, which produces immediate light, and leaves you no choice but to bomb burst out of the illuminated area. Remember that if anyone puts up a rocket flare, it’s for a reason. Similarly, a trip flare or similar device will be positioned to cover an ingress route, and should be covered by enemy fire, as should all obstacles.
The sort of dim light produced by a rocket illumination flare is not really bright enough to completely destroy your night vision. Just don’t look directly at the flare. You can always close at least one eye, or maybe have some of your group close both, if you are acting covertly and the situation allows it.
If you have no night vision devices and need to illuminate an area, either for a hasty attack, raid, an ambush, or a defensive action, then consider the use of parachute illumination flares. This will allow those without night vision equipment to use iron sights or day optics to engage targets. It does not produce a full daylight effect. It produces a dusky world of moving shadows. A little bit of coordination will allow you to put up illumination as necessary, while coordinating the absence of it to cover movement. Note: I know of at least one incident where parachute illumination was used in an ambush, and due to the large smoke signal given off by firing a rocket illumination flare, the firer was killed by enemy return fire. Thus, if using rocket type illumination flares, fire from a flank and from cover.
You can also use powerful white light flashlights attached to your rifle. However, I would not recommend the use of such devices in the open. The use of white weapon lights is best confined to building and room clearance operations, where you are inside and using the white light to illuminate the room and clear it following dynamic entry. If you turn weapon lights on while out in the open, you are just inviting enemy fire. That is also an interesting practical point, the ‘negligent discharge’ of weapons mounted white light. Be careful of accidentally hitting the on/off switch on a weapon mounted flashlight. Such an action can not only compromise your patrol, perhaps your move into your assault position for a raid, but it also washes out everyone’s night vision. Best to remove or reverse the batteries until such time as you are definitely going to use them. Something to consider.
The use of rocket illumination parachute flares also bridges the gap nicely between complete unavailability of night vision devices and the partial availability of same. Perhaps you are occupying a defensive position and you only have a limited number of night vision or thermal devices available. Perhaps you have one device that is located in the OP (observation post), and is used to scan and observe your perimeter. If you get an incursion into your perimeter, and most of your team is just equipped with either iron sights or day optics, then once the enemy is detected you can put up parachute illumination in order to allow all of your team to effectively and accurately engage the enemy. This is a useful bridge use of optics and white light.
In a little bit I will move on to the actual use of night vision devices. What I want to say right now is use them appropriately. Even if you are fully equipped with high-tech night vision equipment, there is potential for the overuse of such equipment to have a negative effect. What do I mean by this? Well, perhaps you are conducting a raid, and perhaps part of the objective is a building. It’s a nighttime raid. In such circumstances it would be ideal for your fire support team to be equipped with night vision equipment in order to allow them to generate accurate fire, and also most importantly to be able to track your progress on the objective and avoid a friendly fire incident. However, if you are the assaulting group it may not be best at all times to go with equipment such as PVS 14. Part of a raid is the use of speed, aggression and surprise. It’s not some Delta force video-game. You may be better off putting up illumination rounds, whether that is rocket flares or mortar illumination, and going in hard. Maximum speed and aggression. That may also include the building, where you could clear it using weapon mounted flashlights once inside the building. It’s just something for you to consider, avoiding over-reliance on technology, which is one of the reasons why your PVS 7/PVS 14 will flip up on its helmet mount and allow you to get it out of the way when you don’t need it.
In fact, if we look at the Falkland’s War in 1982, it was indeed true that the Argentinean’s were equipped with night vision equipment where the British troops were not. The Brits went up the mountains using the basics of fire movement, and white light when necessary or available. They mainly fought up through the darkness using basic fire and movement, with fire support as they could get it. Many of the Argentinean commandos were equipped with night vision sights on their rifles. These were responsible for many of the British casualties. This highlights several things. Firstly, technology does not always triumph over morale, training and aggression. Secondly, the combined use on the battlefield of both old school and modern technology, albeit on opposite sides.
For example, if we move away from the defensive position to a more patrol situation, then let’s imagine that we perhaps just have one or two items of night vision technology within that patrol. Perhaps you have one PVS 14? Perhaps you have a single FLIR thermal imager? There are several options here. Perhaps your lead scout is using the PVS 14 on a helmet mount? This still gives the option of flipping it up or down as necessary. Perhaps even the lead scout, or the patrol leader, have the FLIR on a cord around the neck? Having the FLIR, or the PVS 14, either bungeed around the neck or flipped up on a helmet mount allows you to patrol without them, but then utilize them to scan ground ahead before moving over it.
A little bit on the technology. Your standard night vision devices, such as the PVS 7 or PVS 14, are image intensifiers. This means that they amplify ambient light to produce the familiar green image. On a lighter night they were better, on a darker night not so good. These are passive devices, in that they do not generate anything that can be picked up by an observer. However they are often equipped with an IR flashlight, which can be used to covertly illuminate the area. However use of the IR flashlight device is an active measure which will be seen by anybody else using night vision equipment. Importantly, a night vision binocular or monocular is not a magical device. If you could hide from an observer with the naked eye, you can hide from an observer wearing a PVS 14. Also, it is important to note that if you use a binocular night vision goggle you will lose depth perception. This is why the monocular, such as the PVS 14, is preferable. It allows you to retain night vision in the unused eye, and allows you depth perception.
A thermal imager, or FLIR, uses a different part of the IR spectrum than an image intensifier, and detects heat emissions. Therefore the picture you see is made up of the heat differentials observed. In that sense a thermal imager is a little bit more magic than image intensifier. These devices are great for static observation. With a small handheld FLIR device, about the same size as a PVS 14, you are looking at a tiny little video screen. In my opinion, such a device is best used for periodic scanning in a static OP, or if out on patrol scanning from a static position over the ground ahead.
With both of these devices, the use of terrain, vegetation, and adverse weather conditions, to mask your movement, will be effective. Thermal imaging is a little bit harder to defeat because if you heat up objects around you, there is a chance that you will be seen.
If you are mobile, rather than in a static OP position, then in my strongly held opinion there is a best way to mount and use these devices. In a static OP there is no reason why you cannot use an image intensifier or thermal imager just like a set of binoculars, by having them around your neck and using them for routine scanning. You can also do this while on patrol. If you have image intensifier such as a PVS 14, then the best thing to do with it is mounted over your eye on something like a helmet. The helmet mount will allow it to be flipped up and out of the way as necessary. You don’t want your night vision device mounted as a sight on your rifle when on patrol, simply because you can only use it when aiming your rifle from the shoulder. If you want to patrol with the benefit of the PVS 14, then have this monocular device mounted over your eye so you can actually use it as you walk along.
If you also carrying a handheld FLIR thermal imager then I recommend you keep this to hand in a pouch or hung around your neck. You can then stop, flip up the PVS 14, and scan with the same eye using the FLIR. If it matters to you, this will also preserve night vision in the unused eye.
Of course, having a monocular night vision device mounted over your eye, most likely your dominant eye, will give you difficulties if trying to engage enemy with your rifle. The solution to this is a weapon mounted IR laser, zeroed to your weapon. This bridges the gap between what you can see through your monocular and the fact that you cannot use your sights. You can buy civilian legal versions of the military device, which will allow you the low power IR laser setting, which will give you effective engagement distances out to maybe 100 or 200 m, which is all you need. To engage, you simply turn on the laser with the switch mounted on your hand guard, point, picking up the laser dot through your PVS 14, and shoot.
The question often comes up of how to mount your night vision monocular to your head. The provided ‘skull crusher’ is not popular. The most effective way to mount this device is on a helmet. But no one wants to wear or carry a helmet. Well, I disagree. There are a couple of options: you can wear a ‘bump style’ ProTech or air soft knockoff tactical helmet which will comfortably mount the night vision equipment while being lightweight. If you want ballistic protection you can buy a MICH or ACH helmet off the Internet. You can also purchase lighter ballistic helmets such as the ops-core FAST helmet. Pretty high-speed looking! Only you can decide what you’re prepared to wear. Yes, I know that a ballistic helmet does not stop direct strike from high velocity rounds. But depending on the situation, if you’re going to carry a helmet for your night vision equipment, it may be worth carrying one that is also ballistic protected. You never know what it may stop. If you are doing covert stuff, then just carry a skull crusher and suck it up. Each to his own.
I will say this, in my opinion, it would be better to have one battle rifle equipped with an IR laser, have a PVS 14 mounted on a ballistic helmet, and a handheld FLIR thermal imager, than a safe full of rifles and no night vision capability. You don’t have to use this stuff all of the time, but if you have it you have the choice of using it. For example, if you are hidden out someplace with your family after the SHTF, it’s going to be dark out there keeping watch at night. With a PVS 14 and a FLIR you have the excellent capability of being able to scan your perimeter and pick up threats. You can even use these devices on ground domination activity patrols (GDA). Yes, I’ve told you that you can work out there at night, but the flipside is that without the equipment your visibility is seriously impeded, and without electric light it is very dark out there.
So now we get to the other end of the scale. You, and the rest of your tactical team, have invested in this equipment. This means that you are not at a disadvantage against any aggressors who are similarly equipped. You don’t have to patrol all might with your PVS 14 over your eye, you may not feel it is appropriate or that the threat is high enough at all times. But you have the ability to flip it down and see what’s out there. You also have the ability to pull out your FLIR thermal imager and scan the next phase or bound of your patrol movement. That’s a pretty convincing sales pitch for night vision equipment, right? Where’s my commission? LOL. I know that I want to be able to scan ahead of me and pick out that ambush force before I walk into it, if I have the chance to do so.
One of the big problems with night vision equipment and thermal, is the expense. I refer back to what I said above about the number of rifles you have. Sell some: how many rifles can one man carry anyway? Night vision and thermal equipment is such a game changer that I believe it is worth the sacrifice to invest in it. At the very least, you want one PVS 14 (or equivalent) and thermal imager for your family group. I refer you back to my comments on the use of white light and parachute illumination flares for situations when you need to engage but not everybody is equipped with night vision optics.
A little earlier when discussing raids, I touched on the dangers of fratricide. This is something that needs to be taken very seriously. Given that an assaulting force should properly be sweeping across the objective from the flank of the fire support group, it is necessary for the fire support group to know when to switch fire away from the assault element. It doesn’t want to happen too soon, but it doesn’t want to happen too late. There are various methods that can be used: you can use radios to report objectives reached or phase lines, or something along those lines. You can use other signals such as light or flares. However none of these are foolproof. You want to use pen flares to signal a switch fire? Well, when the tracer is winging both ways up and down the objective and ricocheting off in all different directions, then you may find it hard to spot that flare, even if it is a different color from the dominant tracer. Things have been tried such as attaching light sticks to the end guys in the assault group. Again it doesn’t work very well and it also opens them up to being seen by the enemy.
I’m not trying to paint a picture of doom and gloom, but clearly fratricide avoidance at night poses a challenge. If the fire support group is able to view the assault going in through night vision equipment, then we are in a better place. Oh, by the way, depending who you think your adversaries may be, you may want to get that IR glint tape off your equipment; It reflects back when lit up by active IR from Apaches, in order to determine friendly forces.
In summary, if I found myself without any night vision equipment, I would not consider that sufficient reason to give up. I have spent enough time wandering around the darkness to know that it can be done. However, night vision and thermal equipment is a definite game changer. If there is any danger that your adversaries will have it, and there is because it is widely available, then you should also try and get hold of it too. However, if my adversaries have it and I don’t, then I know where I can find it, right?

Night Optical Device Firing (NODF)
This is an optional class that takes place after the first training day of CRCD classes.
Class start time is 2000 hrs (8pm).
Note: this class is designed for you to bring your own equipment.
Background Reading: Considerations for Night Operations
NIGHT OPTICAL DEVICE FIRING
NODF is designed to introduce students to their night vision, weapon and aiming devices. Students will learn how to integrate different systems to allow them to effectively use their weapon at night. Students will also be shown combat proven TTPs for night time operations. Students will get the most out of this class if they come with quality night vision, a reliable weapon and some form of infrared aiming laser. If you are unsure of your gear please email MVT.
Above: ambush target fro the tactical exercise. This was engaged at night.
NOD capabilities and limitations
Introduction to night operations
Equipment selection and set up
Aiming device zeroing procedures
Tactics, techniques and procedures for NOD usage
Understanding common countermeasures
Night firing: square range and a simple tactical exercise
Functioning, modern, magazine fed, center-fire rifle (ex. AR15 family of weapons, AK47 etc.)
Quality hands free night vision device that will not fail on you, with head mounting ability (skull crusher minimum)
Infrared aiming laser (DBAL type or similar), ability to mount it on the weapon
Ability to carry at least two reloads on your person (battle belt, magazine pouch, chest rig, etc.)
Ear protection (electronic is preferred but we understand the limitations of equipment integration)
Clear eye protection
Positive attitude and an open mind
Seasonally appropriate clothing (obviously the temperature drops at night so be prepared)
Light weight helmet for your NODs or Crye Precision Nightcap (w/ shroud)
Above: Crye Nightcap, PVS-14 w/ shroud, mount and arm
Spare batteries for all electronic equipment
Red lens flashlight
Notebook and pen or pencil
Weapons maintenance gear (lube, cleaning kit, sight or weapon specific tools, etc.)
Knee and elbow pads
Best Set Up:
The ideal setup for this class, which applies to the actual use of night vision gear at night, is:
PVS-14 night vision monocular, head mounted.
You should mount it on a helmet, bump or ballistic type, or a Crye Precision Nightcap with shroud (awesome lightweight option). The standard skull crusher is not ideal because it does not allow you to flip up the PVS-14 (and it crushes your skull!)
DBAL style rail mounted IR laser, preferably with a rail switch to turn it on and off (so you can have a momentary on only option).
Weapon mounted IR flashlight is also useful, although we will tell you when and when not are good times to use this.
Above: PVS-14 on Helmet, either a bump only or ballistic type
If you are able to rig this gear to your head/weapon in advance, that will save time, rather than getting it out of the box on the night. If you don’t have a clue, we will help as necessary. We will give you the basics, and also show you the utility and limitations of this gear. You can’t pull it off the shelf and suddenly own the night! Hours under NVG’s are precious training. If it is dark night and you have never used this gear before, you can feel a frustration and claustrophobia that we will help you with. Training time is vital with this gear.
Under safe and controlled conditions, we will zero your IR laser, get you night shooting, do some controlled movement /target engagement on the square range, and take you out on a simple controlled night ambush on the tactical ranges.
Above: example DBAL fitted on top rail, with helmet with NOD monocular attached.

For everyone on the forum reading this I have a piece of advice.
Get yourself some NODS. There are some VERY exciting things in the works for when it gets dark out. I’ll let Max say more but stand by. It’s gonna get awesome.

Robert is a great guy. He was on one of our NODF classes and though it was a little rough I think he had a good time. If you know anyone looking for NODs send them his way. I don’t have any financial interest in JHR but it’s good to help a friend.August 22, 2014 at 10:49 am #8675MaxKeymaster
Second that.. I purchased my 14 from Robert. Good customer service hes a good guyJune 1, 2015 at 5:49 pm #18030DiznNCParticipant
I would like to add a ditto to this post. After taking the NDOF course, I am a believer. Although this stuff is expensive, if you can swing it, do it. Sell all your collector guns n gear. Sell all your other toys. Get some NV capability if you can.
It is not a be-all, end-all. But if the oppo has it, then you might need it as well.
