What weight should ammo cans be filled with for the AL event?

For the ammo cans used in the Assault Load (AL) event of the Marine Corps Combat Fitness Test (CFT), the correct weight is 30 lbs of sand. This specific weight is designed to simulate real-life combat load scenarios in which Marines may need to carry heavy loads over distances. The purpose of using 30 lbs is to ensure that the test remains challenging while still being manageable for participants to safely and effectively perform the required exercises.

Utilizing a lighter weight, such as those suggested in other choices, may not accurately represent the physical demands placed on Marines in actual operational environments. Hence, the established weight of 30 lbs is a balance aimed at testing endurance and strength without compromising safety and effectiveness during the event.
