IR Strobes are used for PID in either a tactical or rescue operation. Depending on the capability of the operator IR or even SWIR lighting can be used to positive ID.
Why use Short Wave Infrared SWIR strobes?
SWIR lighting and strobes allow IR to be seen in a greater spectrum of conditions including daylight, heavy fog and yet cannot be seen by the naked eye. The SWIR spectrum is also easier to see from satellites.
