In completely other news it was interesting to see how what I learned by playing Myth 2 tournaments and the grand campaign of Close Combat 2 A Bridge Too Far (re enactment of Operation Market Garden with authentic location maps) actually works irl. Some basic things to take from this which worked very well vs NATO:

1) Hold the line. Let the enemy come, the attacker always loses more and if you can stall long enough you can wait overnight and regroup.
2) Attack when it's "free". Only rush the enemy when they are weak and close.
3) Hit hard on their strongest force to demoralize. Self explanatory, if they can't win with elite units, what can the rest do?
4) Shoot at them even if you can't hit them. Being shot at is scary and mentally tiring. Conserve ammo but you don't have to only shoot visible targets, just wearing them down also matters.
5) Long clear lines of fire. Don't hold forward positions, you will lose soldiers and the line itself sooner or later. Retreat to a safe location and make the enemy step out on the field, then obliterate them without exposing yourself.

And finally:
6) Dumb strategies work, because armies are dumb organizations. A two prong assault is something everyone can understand, this means it will happen if you decide on doing that. complicated shit that the grunts can't grasp won't work.
