Which principle is recommended to rotate ammunition stock to prevent aging and degradation?

• A. First-In, First-Out (FIFO) principles.
• B. Last-In, Last-Out.
• C. First-Out.
• D. Random selection.

Answer: (A)

Rotating ammunition stock to prevent aging relies on using the oldest rounds first. Ammo components can degrade over time due to moisture, temperature changes, and primer or propellant aging, which can compromise reliability and safety if long-stored rounds are issued. Using the oldest stock first minimizes how long any given round sits in storage, reducing the chance that aging will affect performance. It’s practical because you can track lot numbers or dates and rotate stock during issuance, keeping the inventory from aging in place. In contrast, issuing the newest stock first or selecting rounds at random doesn’t control age, so older ammunition may sit longer and introduce variability in performance.
