What is the safety for a projectile with HE and MT?

• A. He, Frag, Move, C/S
• B. He, Frag, Move, VT
• C. He, Frag, Move
• D. He, Frag, Move, C/S

Answer: (D)

When a projectile contains high explosive and a mechanical time fuze, you’re dealing with two hazards: the blast/fragment hazard from the HE and the risk of delayed detonation controlled by the timing fuze. The safety label must reflect both aspects. Including the four elements HE, Frag, Move, and C/S communicates that you recognize the explosive/fragment hazard, you need to move to a safe distance, and you must address the fuze’s timed safety condition. This is why the option with all four terms is the correct one for an HE projectile with a mechanical time fuze. Replacing MT with VT is incorrect here because the fuze type is mechanical time, not variable time, and omitting the C/S or MT-related precaution would understate the safety measures required.
