Just a quick clarification: I THINK I know how this works, but I want to make sure.
Surface warships control the Sea Zone they are in. In addition, Cruisers and Aircraft control Adjacent Sea Zones (their Zone of Control).
Submarines: Submarines may freely move (both tactically and strategically) through enemy occupied sea zones as well as enemy ZOCs without initiating combat. Likewise, enemy naval units may move freely through enemy submarine occupied sea zones (both tactically and strategically) without initiating combat.
Reading from this, Submarines do not actually control the Sea Zone they are in. They may attack units that move through (Movement Interdiction Combat), but they do not control the sea zone.
Supply -
You may not trace supply through Sea Zones that are controlled by the enemy. The rules repeatedly state "Surface Naval Units" as blocking supply, over and over again.
So, my read is that Submarines, by themselves, DO NOT BLOCK SUPPLY.
Is this correct?
