Which weapons are authorized for storage in the small MAWC?

The authorized weapons for storage in the small MAWC (Mobile Armory Weapons Container) typically include the M4, M16, and M249. These weapons are part of standard military inventory and are commonly used for various operations due to their versatility and compatibility with other military systems. Each of these firearms serves different functions; for example, the M4 is a carbine providing a lightweight option for troops, the M16 is a standard-issue rifle known for its accuracy, and the M249 is a light machine gun that provides suppressive fire.

In contrast, the other options contain combinations of weapons that would not typically be housed together in a MAWC due to specific operational roles or incompatible storage regulations concerning weight, maintenance, or usage. Each of the selected weapons in the correct answer aligns with standard military protocol for storage and deployment, making it the appropriate choice.
