Convoy Raiding

Convoy Raiding is a critical goal of any navy as it allows you to cripple enemy trade routes and restrict their access to essential resources such as oil and rubber. By blocking supply to troops overseas, you put remote islands at risk of destruction.

While I generally advise against naval technology research (as the navy supports and assists the army), I make an exception for submarines.

They improve significantly over time, and the 1940 Submarine, combined with Snorkel, is incredibly hard to detect without proper patrol vessels.

For maximum efficiency, I recommend using Submarines in groups of 10.
