I'd like to see a kayak just so I could paddle under the Nogova bridge, rig either side with satchels then swish off and wait for a load of commies to walk over it... ;D
It'd be a good alternative to parachuting in or being heli'd in, just creeping along the coast in the wee hours of the morning.
Oh, there was a Vietnamese Sampan in the Nam Pack v2, but it looks out of place anywhere but on the Ia Drang map.
