Which of the following is NOT a common mechanism by which explosive munitions cause injuries?

The correct choice reflects that "Supplementary" is not recognized as a common mechanism through which explosive munitions cause injuries. Explosive munitions typically cause injuries through defined mechanisms such as primary, secondary, tertiary, and quaternary effects.

Primary effects refer to injuries caused directly by the blast wave and pressure changes, which can lead to shockwave injuries to internal organs. Secondary effects involve injuries from shrapnel or debris that are propelled by the explosion, which can cause penetrating wounds. Tertiary effects result from individuals being thrown due to the blast force and can lead to blunt force trauma. Quaternary effects encompass a variety of other potential injuries, including burns, respiratory issues from inhalation of toxic fumes, or crush injuries.

"Supplementary" does not align with these established mechanisms and therefore is not commonly used in the context of injuries caused by explosive munitions. This distinction highlights how explosive injuries are categorized and helps in understanding the nature and treatment of such injuries in medical and military contexts.
