How many major mechanisms do explosive munitions typically injure through?

Explosive munitions typically injure through four major mechanisms. Understanding these mechanisms is critical in assessing the injuries sustained from explosive events, which can be complex and varied. The four mechanisms include blast overpressure, which can cause severe internal injuries due to rapid pressure changes; fragmentation, where shrapnel from the explosion can penetrate and damage tissues; thermal effects, which involve burns from the heat generated by the explosion; and positive and negative phase impulses that can lead to other traumatic injuries. Each of these mechanisms plays a significant role in the overall pattern of injury observed in victims of explosive incidents, which is essential knowledge for medical professionals treating such injuries.
