CORPS under water thing
When the Joe SEALS, Torpedo or Wet Suit, need to get into a location under the radar or under the noses of Cobra they use an underwater submersible. This small craft allows for near silent maneuvers into unfriendly waters.
Designed as either a one or two way vehicle it can be outfitted with explosives and positioned in such a way to weaken or distract enemy forces.

This little thing came with a CORPS boat I bought a while back. I decided that the Gunboat Grey would work well to cover up the original colors.
