Hi 22, i have started work on this small scale indeed acouple of weeks ago for modern battles...
Quick ideas i had...
Infantry stand...
1. you get 1 d6 damage dice for " all assault rifles "
2. if you have a Mg etc, you add 2 extra d6
So a infantry section would have 3 d6 to attack with
One hit with out save will remove the stand,
With Tanks, all i did was remove the "Tough" hits rule, so all tanks are killed with 1 hit, all weapons are weaker by 1 point, so a main tank gun is -3 not -4
Suppression, i had rules for tanks and aircraft can be suppressed as well, i mean if you was driving though a war torn street and get hit by a rpg, you may lose a action over the surprise hit...
Aircraft, that lose 1 action can still action, but 2 actions lost, means you have to left the battlefield, as the sky is not safe for a few turns...
Etc,Etc
