Wow, Patria actually did it. They made the Patria AMV 28A capable of swimming from ship to shore. According to this vid it can handle sea state 3 which is better than what many other supposedly amphibious vehicle can do (looking at you K21).
Flotation armor might be the biggest thing to hit in decades...the main problem is that it adds so much volume to vehicles. Regardless this is a pretty good glimpse into what Patria will be offering customers.
