Which munitions item is not loaded into transport modules by munitions personnel?

The 20mm munitions item is not loaded into transport modules by munitions personnel due to specific operational and logistical guidelines that govern ammunition handling. Typically, larger caliber munitions, such as 30mm, 40mm, and 50mm, are managed in transport modules considering their weight, size, and the way they are utilized in aerial or ground operations.

The 20mm rounds are commonly used in firearms like the M61 Vulcan cannon, and the handling requirements for these smaller munitions differ significantly from larger artillery. This distinction is important for ensuring safety, effectiveness, and efficiency in munitions management. Munitions personnel are trained to handle various types of ammunition, but certain calibers, like the 20mm, may be integrated into systems differently, which is why they are not handled in the same manner as the other larger calibers.
