The Combat Identification Panel
, also known as the 'Coalition Identification Panel' or simply 'CIP', is a device mounted on military ground vehicles to distinguish them from the enemy during battle. They were developed after the first Gulf War
to reduce friendly fire
incidents among allied ground forces. These panels are designed so as to produce a distinct and easily-identifiable Infrared
signature when seen through thermal imaging
systems. CIP panels first saw widespread use in Operation Iraqi Freedom
where nearly all coalition vehicles were equipped with these devices, usually mounted on the sides and rear of the body and/or turret. Some were even mounted on the driver and front passenger doors of Humvees
with a special cutout so the door handle could still be accessed through the panel, as well as on the hood between the windshield and the top grille.
