Buoyancy problems in amphibious tank 2S38

I was in a fight on the river with the 2S38, and I drove my vehicle into the river, but I immediately had problems. I almost drowned. Then I tried to drive through the river, and it started jumping above and below the water like a submarine jumping or a dolphin. It was very difficult to aim, the vehicle’s sounds were inaudible, especially the gunfire. I couldn’t see the shot through the gun’s sight, and I was easily killed.
