THERMALS

Governments spend billions on thermal optics annually yet train their most elite forces on targets that fail to produce a realistic thermal signatures. SISU/ARMS built the HEAT SIG to generates a persistent, combat-representative thermal signature that reflects what operators see through thermal optics in real kinetic environments—across weather conditions, day or night and extended training cycles. Designed for durability and repeatable use, it enables operators to train, validate, and master thermal systems against real heat signatures, not artificial stand-ins.
