@Big Boss No, I don't think this is possible without a DLL

Do these new improvements allow atomic bomb or Nuclear Missile interception? I'm not 100% but I remember reading that vanilla AA units couldn't intercept those

With the increase in exp sounds doable will give them a try in my next game.

As someone who detests air power, I salute you.
I absolutely adore watching air units fall from the flak-filled sky.

This is because they only receive 2xp from interceptions, I'm going to raise this value to 5xp in the next update so promotions are easier to get

OK possible - But I must admit with over 11k hours in game I do not recall ever getting a highly promoted AA unit.

Correct, but by the time AA guns are produced they will gain 2 promotions from an armoury, allowing them to reach their original damage. As opposed to the wasted promotions like drill and shock. The debuff is offset by the new promotions being extremely useful against aircraft. Quick Fire = more interceptions = more units saved + more xp

I have a question - after reading this - " The base bonus vs air/helicopter units is now set to 50 (originally 150), this can now be increased to a maximum of 200 from the flack promotion "
Am I correct in assuming with this mod AA starts out MUCH weaker than originally and need multiple promotions just to get to equal strength ??

Very nice mod!
