NUKE .50 BMG Calibre Pistol

its completly posable and actualy practical for use with heavly armored vehicles groups of soft targets and yes to eliminate any trace of a small object the “bullet” style igniter could shield the radiation. This would put the explosive capability of a pound or two of TNT. The army has already adapted it to mortars so going along with the military theory why not put a nuke in every solders hands lol
