Abstract: A weapon for tactical simulations provided with at least one projection device of electromagnetic beams to simulate the projectile fired by the weapon. The projection device includes a plurality of emitters of electromagnetic beams housed in projectors, each susceptible to emit electromagnetic beams having geometrical parameters different from those of the electromagnetic beams emitted by the other emitters so that each beam emitted realistically simulates a section of the path that the projectile to be simulated would cover. The weapon further includes an adjusting system of the electromagnetic beam emitted by the emitters to vary the geometric features so that the overall electromagnetic beam has, for all the path that the projectile to be simulated would cover, geometric features with values includes between predetermined intervals so as to realistically simulate the projectile.
