No multiplication, just all effect at the same time, one ship on one red area do max damage already, more don't add anything for that part. Two obviously add the blockade damage too, but no double red damage. Both can do convoy raid, if near the route, but in this case, you are better with the port blockade, bringing it below 5, and the convoy route gone (turned into white and no mpp from it, until the port repaired, unless alternative port is an option, like the soviet one for receiving.) For port damage, you can also just bombard with surface ships, to save time, at the cost of your ships health.
Solid, dude. With a cool name Xsillione, & gaming knowledge, we might need to square up on the battlefield.
Until next time, may your mortar fire be long & on target.
Take a ton of bolt and steel
A whole lotta sweat, a set of wheels
On the Speedway
The flag is down, pistons pound
Plenty of engines ripping around .. on the Speedway
