I am playing my first game as Germany, and I noticed that when I attack, it costs 2 APs, but when everyone else attacks, it costs 3 APs. Germany is at level 2 doctrine (now up to lvl 3), and everyone else is at level 0 or 1. Is this the reason? Will I see that everyone else gets attacks for 2 APs when they get to level 2 doctrine? Will I ever get to a point where attacks cost 1 AP? Thanks!
