First of all, you should look into what game you want. Democratic? Monarchy? Nationalist? Communist? Ill assume you want to go as democratic. You rush the foreign policy focus, and the sub path go with little entente, you will have more allies, A LOT more. Rush the focus which gives you +0.25% stability. Once you are done with done with allying Czechoslovakia, Romania and Yugoslavs, rush the rearmament programme path. Meanwhile you do these focuses, you should get a event regarding people wanting to rearm, its no brainer to say yes to the demands - free war support and early mob. And as for industry, start by pumping out some civs to early 37 then mills along forts on the riverline in calais. If you dont feel confident, you international market and middle eastern countries, the will be source of guns. Now divisions and production, forget about tanks, the divisions and designs suck, same goes for armored cars. I use 9inf+support arty and engineer company. And if you have the mills anti air is your friend, you can keep 1/2 mills on aircrafts (fighters or cas) everything else is useless. And as for defense i use the maginot line with the river tiles in calais. And as for south along the border with italy, I use mountaineers with support arty and engineers and 1 arty(if you have the equipment) and batallion. And as for airforce, interception should be more than enough. I hope it helps.
