HGU-55 FlSt 18 BLACK TAPE
"Fliegerstaffel 18" Black taped HGU-55.
The 18's squadron logo is a black panther on green background. Due to this a layer of black reflective tape has been applied to the helmet.
The connector near the RH nape strap screw is for the OMARA (a system similar to the more common CEP) pilot customized comm and noise reduction earplug harness.
Since 2008, during scheduled maintenance, all helmets have been upgraded with this system.
