First. Awesome find Slowman! Good job! Next. Looks like the Japanese are working on both a tracked and wheeled test bed for a "Future" AAV.
Personally that makes me cheer. I wonder if the USMC is monitoring their work. The Japanese are motivated to get a solution and they have a long history with amphibious vehicles (well during WW2 but you get the idea).
I wonder though. Have we gone from world leaders with the original LVTP series to now depending on others to develop amphibious armored vehicles?
