An adapter assembly permits sensory feedback such as a pain penalty to be incorporated into a combat training system of the type which includes simulated weapons which output a laser hit signal representative of a projectile and user monitoring devices worn by participants having laser sensors to provide an indication when a participant is hit by a simulated projectile in a combat training exercise. The adapter assembly works with an electrical impulse device also worn by the participants to deliver an electrical shock to the participant in response to receiving an activation signal. More particularly, the adapter assembly has input sensor for sensing when a user monitoring device indicates a hit to the user, and a signal output for generating an activation signal which can be received by the electrical impulse device to shock the participant when hit.
