I agree with this however this idea is very entrenched in players minds as the “japanese style attack” Perhaps instead of infantry we could go back to special Japanese fighters with a modifier +1 on attack and cheaper to allow the initial Japanese advantage of the “lance” torpedo which the US had no equilevant too.
so:
Japanese fighters cost 6 IP and get a +1 attack on naval ships in the opening combat round
OK now back to some other ideas:
German Blitzkreig: these units get a +1 combat modifier against enemy ground units in every round where no enemy fighters are present. They also give one armor unit a +1 attack with each paired unit at a 1/1 basis.
UK home defense: British fighters defending in home territories get a +1 defense modifier
Soviet Shock armies: Soviet armor units in the opening round of combat get premtive attack in the first round of combat
Japanese: allready covered
USA: “blood and guts” all armored units ( and mech infantry) can attack one territory and if they take it can continue onto a second attack in an adjacent enemy controlled territory .
Or you can install some US marines type of deal…
