1. A nonexplosive training munition, comprising:
a projectile configured to be propelled towards a target, the projectile having a projectile outer shell that has an aperture;
a signature source assembly attached to the projectile outer shell adjacent to the projectile outer shell aperture, the signature source assembly configured to illuminate an observable signature without an explosive signature;
a trigger assembly housed with the projectile outer shell and in communication with the signature source assembly to initiate an activation of the signature source assembly upon the projectile reaching the target; and
a boat tail assembly that, in a first position, covers the projectile outer shell aperture and encloses the trigger assembly and signature source assembly within the projectile outer shell, wherein the boat tail assembly is urged by the trigger assembly during the initiation to a second position separate from the projectile outer shell to enable observable exposure of the observable signature,
wherein the signature source assembly upon the activation produces the observable signature without a pyrophoric ignition.
