The Laser Aim Scoring System (LASS) is an infrared (IR) Laser detection/scoring system used to evaluate Hellfire Missile engagement procedures and techniques. The system is optimized for the AH-64 Apache and AH-58D Kiowa Warrior helicopters, but is capable of training all laser designator operators. The LASS provides a live-fire range capability for evaluation of target presentation procedures and precision measurement of the Laser designator operator target tracking capability in a compact, portable system.
