is it true that when u fire artillery beside putting your hands over your ears, opening your mouth is a "must"? or the concussion of the artillery will burst the eardrum?
Thought you have to wear earplugs + ear mufflers?
*I not too sure... I'm infantry grunt, not arty*
of cos no lah...
FYI, when doing live firing, the gunners do not wear their helmets cos it simply won't fit when they put on their mufflers + ear plugs!
no that is not true. even if that is true, your nose is always open
