What are the two primary causes of corrosion in ammunition storage, and how does Module 6 mitigate them?

• A. Condensation and rust; humidity monitoring only.
• B. Temperature fluctuations and sunlight; insulating and shielding.
• C. Moisture ingress and humidity; climate control, sealing, and moisture monitoring.
• D. Vibration and dust; cleaning and vibration damping.

Answer: (C)

Moisture in the storage environment is the main factor driving corrosion of ammunition. When moisture enters the storage space or the air inside becomes highly humid, metal components oxidize and primers can deteriorate, increasing the risk of corrosion. Module 6 tackles this by focusing on two related aspects: preventing moisture from getting in (moisture ingress) and keeping the air inside dry (low humidity). It achieves this through climate control to maintain stable, appropriate conditions, sealing to stop water from seeping into containers or rooms, and moisture monitoring to continually track humidity levels and trigger actions before corrosion can start. By actively managing both the presence of moisture and the air’s humidity, the storage environment stays less conducive to corrosion. Other factors like temperature swings or sunlight aren’t the primary culprits in this context, and while debris or vibration can cause wear, the corrosion risk in ammunition storage is most effectively addressed by controlling moisture.
