Abstract: A portable apparatus having the shape, and intended to simulate the firing, f an actual rocket launcher. The simulated portable rocket launcher, used in conjunction with a laser device, comprises a tubular casing having mounted thereon an aiming device. A unit of similar shape designed to be inserted in said casing, has front and rear end plates between which extends a bar surrounded by a spiral spring, an annular shaped mass representing a rocket being movably mounted through its annulus on said bar. Locking and triggering means are provided to secure the mass to the rear end plate in a ready-to-fire position, while a resilient stop member for the movable mass is provided at the front end plate. Activation of the triggering means releases the mass from the rear end plate and activates the laser device which directs a beam on the target. Movement of the mass along the bar is terminated at the front end plate by the resilient stop means.
