As I understand it. There are 10 active Army divisions? 1st Armor, 1st, 2, 3, 4, 25 Inf, 10Mt, 82, 101 airborne and the 1st aircav. Yes?
Is there 3 active Marine divisions?
Now the question:D How would the inactive divisions be filled out if needed? Are they completely stood down? Would new recruits or draftees be needed to round them out?
