It should be a percentage increase at each mil tech tier that gives mil tactics. Right now the early techs matter wayyyyyy too much because it's a flat 0.25 at each tier. Going from mil 3 to mil 4 gives a full 50% increase while going from 31 to 32 gives a measly 9% increase. It makes the early game a race to mil 4 so that you can stackwipe equal-sized armies...
