Yep, a lot of stuff you can do here. Â Can buy 1 turn eastwards or southwards. Â Can make a huge fortress square with a navy, airbase, all of that.
Problem is that if you go for the major, you’ll be spending all your money on that and troops for it, which sort of limits the other things you can do. Â With the stuff all showing up buried in your heartland, it won’t be forward placed to attack/defend against the Western Allies, its an all Russia strategy. Â Usually, because of the Baltic German Navy, you’ll be able to tear Leningrad apart from 2-3 directions, but with all your eggs will be in this southern basket, you will probably be emphasizing drilling into the Russian money south and getting the 12 income that’s down there and the oil. Â If you just do the minor, its not as much of a commit but it doesn’t change as much either. Â
And with the german navy in the northern sector, you get the dual threat of sea lion and Leningrad–the navy gives you the same additional mobility as the industrial complex (trading 2 turns of movement for 1) but with more threat projection and choices.
At least in my experience, the mobility pieces are simply better for their cost (mechs, mostly), and these can pretty much make up the same distance as the forward placed base does, but with not as much expense. Â It is still only 1 space closer Romania to Moscow vs Germany to Moscow and the placement of Bessarabia and the marshes mean that its not a direct path.
Its a fairly vanilla strategy to place this base. Â #1 Â you don’t need the extra capacity you start with 29 units per turn #2 it shows your plan off early #3 limits your choices by committing all your resources
One pretty cool idea that one of the posters laid out recently is build the thing, then have Italy take Bessarabia or E Poland and start the war, having all your Romania mobility roll through that gap as one big stack. Â Like the plan, but its not a huge surprise and you have to wait until T3 to get any built units rolling through.
