Which document addresses corrosion assessments on all USMC tactical ground and support equipment?

• A. Tm 4750
• B. Mco 4790
• C. Cat 2
• D. Tm 4795

Answer: (D)

Corrosion assessment in the Marine Corps relies on a dedicated reference that lays out how to inspect, classify, and treat corrosion across every piece of tactical ground and support equipment. The technical manual assigned to this task provides the standardized procedures, inspection intervals, severity criteria, and repair or mitigation actions needed to keep equipment combat-ready. Because it specifically targets corrosion prevention and control for all Marine Corps tactical gear, it serves as the authoritative guide for these assessments.

This is why the manual focused on corrosion (the one with the corrosion prevention and control scope) is the best answer. The other documents cover different topics or broader maintenance areas and do not provide the same comprehensive, corrosion-specific guidance across all equipment.
