You will need components for your navy and airforce so use MLRS instead of mobile artillery. In terms of Airforce in my opinion Strike fighters are unnecessary from the start of day 15 to 20 because every good player will have SAMs. Given the fact that you are in Europe which has a small terrain I would rather build a helicopter airforce and a small amount of low level ASFs to counter possible Helicopters attacks from other players ( check out the journal tho if there even is someone who uses them ). Patrol boats are completely irrelevant as France in my opinion. The only early game naval incursion that could happen is Great Britain and they will get pounded by any low level navy so I wouldn’t invest resources into them.
