IMHO i used this doc some time and it just need:
1. Rework of ptabs - give engine damage like regular snare works, it will help to chase enemy armor.
2. Replace ML-20 to another ability - mark target could be very good, but it also can make balance issues when used togetger with ptabs. More better give some specific ability: like "Smell of prey" (sounds stupid, but good reflect identity) passive ability for all your light and medium tanks, they will get speed bonus when to them near enemy armor with crippled engine or with shocked crew (after hit on light AT-mine or after ptabing).
The main power of this ability are at-cons, they are very powerful, but...hunter is someone who chasing his prey, while in this doc...you don't have anything for chasing. All abilities are very static and it always meaning that you must wait your enemy to catch him in trap. It's very close to brits sim-city, OKW and OST defense doctrines, in terms of gameplay. More proper to call it "Advanced anti-tank defense". But while other doctrine gives you not only AT defense, but AI also, in this doctrine you have all abilities works only against armor.
It will not cause a balance issue as mark target and il2 co exist in isu guard commander.
I think to make this commander replace tank camo with recon and ml20 with b4.
I don't know about you guys but soviets have limited commanders with recon. Not even airborne commander has recon.
