A lot of small arms fire or an RPG turns an air cushion vehicle into a non-moving vehicle if on land, or a barge if on the water. That is why U.S. Navy LCAC's are intended to operate only as fast logistics craft, not primary assault craft.

A five degree egress slope is a pretty standard landing craft parameter.

I should know but I don’t: does South Korea have any well-deck ships to transport these craft?
