Su-Ki Japan
The Su-Ki is also a amphibious troop carrier but unlike the DUWK its more heavier and longer bc in Japan everything is bigger and it started service in 1943 and 193 where made most didn’t live today but it has tall walls and a minimum of 5mm of metal for small arms and explosives and choppy seas it has an option for a tarp on top too but most likely wouldn’t be added
