A bullet causes tissue injury in three main ways. First, it directly crushes the tissue as it penetrates leading to what is referred to as the permanent cavity. The size of the permanent cavity is largely dependent on bullet size and design.

CONT

Les fusils de combat modernes, comme l'Armalite, l'AK 47 ou le M-16, ont des vitesses initiales supérieures à 1000 m/sec. L'orifice de pénétration de ces armes est petit, à peine plus grand que le diamètre du projectile lui-même. La cavité permanente est généralement plus grande que celles de projectiles à basse vitesse, particulièrement si le projectile se fragmente.
