Battlefield Identification System (BCIS)

972

An encrypted question and answer system using millimeter wave (38GHz) technology to identify friendly vehicles in less than a second, out to ranges of 5,500 meters. Such device Affords the gunner critical shoot-or-no-shoot information during combat, interlinked with the firing procedure. If the target is equipped with BCIS, the gunner taking aim will receive a flashing red dot in his optical sight combined with audio voice signal “Friend”; if it is not equipped the gunner will receive response “Unknown” in order to take further action. Unfortunately, BCIS was scrapped by Pentagon in 2001.
