Currently, there is a crowded batch of terms used to describe friend or foe (IFF)  protection:

IR, infrared, subdued IR, reflective, retro-reflective, glow tape, glint tape, near-infrared (NIR), far infrared (FLIR), glow in the dark, and more.

 “What is the difference and how do you know what is right for you?”

This is a common question for those seeking friend or foe protection.

Because each film on your infrared patch performs for a specific circumstance, it is critical you wear the correct protection.

For example, you don’t want a non-covert patch if your goal is to stay hidden.

Here we pull back the weeds and clarify the differences.

In the end, staying safe, completing the operation, and returning home is the goal. 

IR Reflective Film

The most popular of IFF films dates back to WWII. Night vision devices were deployed during the conflict. This is when the term “IR” was born. There are 2 types of IR reflective film – Field and Garrison. Field IR reflective is covert and primarily used for battlefield operations. Garrison IR reflective is used for non-covert detection on the base. 

Field IR

Covert film (black) for stealth movement on the battlefield to stay hidden from the enemy. Reflects your position to night vision only.

Detection: Night Vision Device, Night Vision Goggles (NVG), White Phosphorus NVG, Lidar Technology

Other terms used: IR, glow tape, glint tape, retro-reflective, reflective, near infrared, NIR, subdued IR

Garrision IR

Non-covert film (white) for jobs around the base, street patrols, or SWAT. Reflects white light from a vehicle, flashlight, moon, etc…

Detection:  Naked eye (primarily)Night Vision Device, White Phosphorus NVG, Lidar Technology

Other terms used: IR, glow tape, glint tape, retro-reflective, reflective, near infrared, NIR

Thermal Film

Thermal film is a covert film used to distinguish people or vehicles from the enemy, suspect or surroundings. Unlike IR reflective film, thermal film is visible in daylight and darkness. Therefore the film broadens the scope of use to include daylight operation (search and rescue, car pursuits). 

Thermal Patches and Markers

Detection: Thermal Imaging Device (FLIR)

Other Terms Used: IR, infrared, reflective, FLIR, far infrared, mid infrared, passive, no power, reverse polarity, low-e, low emissivity

Photo-luminescent Film

Photo-luminescent film is a non-covert film for jobs in the dark around the base, street patrols or search and rescue operations. No advanced equipment is needed to view the film.  A fully charged patch is seen by the naked eye for up to 8 hrs. in the dark.

Photo-luminescent Patches

Detection: Naked eye (primarily), Night Vision Device

Other Terms Used: Luminescent, Glow in the dark
