Your list makes no sense, why would you cross out Terror Tactics and add anti-infantry tactics which is just Terror tactics but shit.
Coz static artillery emplacements worthless against CAS or Luftwaffe?
Armored Assault has zero elite infantry
And what?
I didn't add tank hunters just because it's a gimmick doctrine.
Being gimmick not makes it bad.
The shock ISU is great, the counterattack tactics is still good (if you build your B4 in your own base your an idiot and won't hit anything). Shock army has 120's, shocks, and 120mm mortars, and the anti infantry strafe, if you coordinate with your team mates they can make up for your lack of call in armor.
No, completely overshadowed by doctrines i listed. B4 would be bombed by CAS before it inflict any serious damage, better to play without commander then go b4 against CAS.
And USF Airborne isn't the only good 4's doctrines, Priests as mentioned earlier are good for smashing OKW HQs and denying space.
Airborne simply best USF doctrine. In 3 sov + 1 USF scenarios USF player should go airborne every game.
