It's kinda imbalanced though, since only Ostheer and Soviets have commanders with both. OKW, UKF and USF players will always have a disadvantage this way.
Every faction has at least one with both, apart from OKW, although OKW do have scavenge doctrine which you could find a work around using deep spawning jaegers and the 105 barrage. OST are spoiled for choice though.
USF:
Infantry Company, Major recon + time on target. (Good)
Armour company, Major recon + Railway. (Good)
Soviets:
Soviet combined arms, Recon + Il2 bombing run.
UKF:
Commando Regiment, Assault (gives recon) + Air supremacy (Best)
Royal Artillery, Early warning + Concentration barrage. (works)
OST:
Spearhead, Recon + frag bombs
Storm, Smoke bombs + Stuka dive bomb
Jaeger Armour, recon + Stuka dive bomb
