Combat Identification: When You Must Be Seen

Two jobs that pull in opposite directions

Every concealment decision has a second half that is easy to forget. A position that has been properly hidden has lost the things that make it recognisable — outline, colour, pattern, heat and movement. That is the whole point against an adversary. The difficulty is that a sensor does not know who is holding it, so the same cover that defeats hostile observation also defeats a friendly aircraft on approach, a friendly drone feed and a friendly vehicle crew moving up at night.

So identification has to be added back deliberately, in a controlled way, rather than left to chance or to the assumption that someone will recognise a familiar shape. The practical goal is narrow: show one thing, to one audience, for as long as the recognition task needs and no longer.

What a friendly marker has to survive

A marker is only useful if it survives the conditions in which the recognition actually happens. That usually means more than one set of conditions: daylight and darkness, direct sun and overcast, dust, smoke and rain, at a range that may be much longer than anyone imagined when the marking was applied, and through whatever device the observer is using — the naked eye, a night-vision device, a thermal imager or a drone's video downlink.

Those devices do not see the same thing. A high-contrast panel that reads clearly by eye in daylight can vanish through a night-vision device; a marker built for night vision can be meaningless on a thermal image, because thermal imagers respond to emitted heat rather than reflected light. Our spectrum primer sets out what each band actually shows, and the note on thermal signature covers why heat behaves differently from reflection.

Passive markers: panels, patches, tape and paint

Most field identification is passive — it reflects or emits rather than transmitting anything, so it adds no electronic signature of its own. Marker panels are laid out or hung where an air observer can see them. Infrared-reflective patches and tape are worn or fixed to vehicles for recognition through night-vision devices. Painted or applied markings give vehicles and equipment a recognisable scheme by day.

The material decides which band the marking lives in. Identification stickers and patches can be applied and removed as the task requires, which keeps the marking temporary by design. Identification marking paint and the wider family of camouflage paints cover the case where a durable scheme is needed on a hard surface. The useful property in all of them is the same: strongly readable in the intended band, and unremarkable in the bands where it is not wanted.

Seen by the right sensor, at the right time

The hardest constraint in this whole subject is simple to state: a marker cannot choose who reads it. Anything visible to a friendly night-vision device is visible to anyone else with a night-vision device, and the same holds for thermal. Marking therefore buys recognition at the cost of some exposure, and the trade is managed rather than avoided.

In practice that means three habits. Show the marker when the recognition task needs it, rather than leaving it displayed through the whole deployment. Keep the marked area to the smallest patch that does the job, instead of covering a vehicle. And change the pattern or code in use over time, so that a marking observed once does not stay useful to an adversary indefinitely. The same logic applies to the sites covered in our guides on fixed installations and depots and on drone-era concealment, where persistent observation is the threat.

Discipline: codes, timing and not becoming permanent

A marking that never changes and never comes off stops being an identification measure and becomes a signature. Fixed markings accumulate: they are photographed, catalogued and eventually recognised by the wrong side, and they degrade the concealment they sit on top of. The discipline that keeps identification useful is the same discipline that keeps camouflage useful — control what is on display, and change it before it becomes a pattern.

Recognition procedures carry as much of the load as the material does. Markers work alongside briefed recognition features, agreed timings and communication, and they are the fallback for the moment when a crew has seconds to decide. Materials should be chosen on that basis: fast to apply, fast to remove, easy to inspect, and easy to replace when the pattern in use changes.

What to specify

Seven questions cover most identification-marking requirements:

• The band — visible, near-infrared for night-vision devices, or thermal. Name it explicitly rather than asking for "IR".
• The sensor and the range — which device reads the marker, and from how far away.
• Permanence — removable, reversible or expendable, and how quickly it can be taken off.
• Behaviour in the other bands — what the marking does where it is not meant to be read.
• Compatibility with the cover — the multispectral net, paint or coating underneath must keep working.
• Durability — sun, rain, dust, abrasion and repeated handling.
• Changeability — a practical way to rotate the pattern or code in use.
