To be honest, it doesn't seem too hard to me. At first the easy Eastern Front A.I.s i found too difficult, but i got used to it, and now i play with normal A.I.s. Maybe you could use more practice? (No offence...)
It seems as if it plays stupidly, rather than reinforce a squad, it goes out with one person with no health and caps my points, no coordination between armour and troops or support. what an oxymoron...artificial intelligence.
