Got a Real-World Weapon or Armor Question? Mk. VI

[Fhaolan]

Wow thats news to me... you don't need any air to shoot a gun? So they work underwater? (I know they have some which do but I thought they had a very special design to work around this issue)

There are problems with guns underwater, but it's not due to lack of O2. It's the water itself mucking up stuff.
