Hey Model Mann,
What country are you trying to invade????
Seriously, I've seen a swamp buggy with two small rockets on each side! They were horizontal, then the guy, by radio control would erect them and fire them off!!! Haven't seen them operate, the boat was in a lhs a few years ago.
If you do that at night, it would look like a tomahawk going off the deck of a battleship
See ya!
