So US attacked with a tactical bomber, a fighter, and a submarine. The Japanese has an aircraft carrier with a tactical bomber and fighter on board, and a transport in the seazone being atacked.
After the initial turns of the battle, USA loses the bomber and fighter, while Japan loses the bomber and aircraft carrier.
Japan has a fighter and transport remaining while USA has a submarine remaining.
My question: since the plane and submarine cannot attack each other, what happens to the Japanese transport? does it get destroyed or does it remain in the sea zone?
