The TOW (Tube launched, Optically Tracked, Wire Command) simulator is supplied as a complete Surrogate laser transmitter. Weapon signature is implemented by optional M22 pyrotechnic actuator. The TOW simulator can be used with a land vehicle, stationary tripod based, or a helicopter mounted TOW missile system.

The operation requires the soldier to remain aiming at the target for the actual flight time. The laser power increases with time, simulating the increasing range traversed by the missile. The maximum flight time is 11 seconds, which represents 3750 m. The simulator also includes a Laser detector module, which enables the transmitter to become a target in its own right. If the transmitter is hit/killed, this information is transmitted to the personnel system of the user via the association unit link, and displayed on that systems display.
