What exactly is the "flash" that sailors wear hoods and mitts to protect themselves from? Is it actual flame, or is it just a surge of heat, as I imagine that heat travels well down enclosed compartments and tight corridors after a weapon hits a ship!
Why is it that when you see photos of RN sailors at action stations they all have their anti-flash on, whereas when you see photos of USN sailors they seem to be lacking this kit? Also photos of submariners and aviators never seem to include them wearing the same white hoods and mitts. I know they work and fight in different surroundings but surely whatever this flash effect is, it could affect them as badly as any surface sailor!
Why is it that when you see photos of RN sailors (not just engineers) at action stations they are all wearing coveralls over their Action working dress? If the AWD shirt, trousers and jersey is flame retardent, and it is marked so, then how come the coveralls are needed? And why do you see some in white coveralls but most in blue? Are the ones in white coveralls the officers and the ones in blue the ratings?
Why do sailors appear to seldom wear their helmets and never wear body armour? With the possible exception of boarding parties?
