The Phoenix JR is an Infrared Beacon which is powered by one nine volt battery. The Phoenix JR delivers a powerful infrared flash which can only be seen with night vision equipment such as the AN/PVS-7 B/D, AN/PVS-14 and AN/AVS-9 at distances of over five miles and can also be seen through clothing and underwater.

Originally designed as an antifratricide device to help minimize friendly fire mishaps, the Phoenix JR has seen service in Kosovo, Bosnia, Somalia, Afghanistan and Iraq. The Phoenix JR has proven itself useful in both Combat and Covert operations, some of which include: identifying personnel and friendly forces, marking vehicles and convoys, outlining safe pathways, trails or installations.
