I asked my son- he was 11B so different paygrade- said all he can be sure of is- they’re warheads!
Well, we mark our weapons with colors and codes, I believe the soviets or whoever he gets them from, do also, yet those have no markings that are distinct or strike out, nor are they stored in any special manner to prevent leakage of the agent, they are basic storage boxes!
NO FOOL would do that, regardless of their religion
