Sturm officer should be able to gain veterancy as other units. His aura should scale with veterancy (that applies to all auras)
Emergency repair should come inline with similar abilities
Panzer commander should become cheaper and the barrage should become weaker (incendiary?)and cheaper
Sturm Offizier should also lose the mechanic that all squads in close proximity retreat when the officer is killed. The aura is nowhere strong enough to justify that imo. Focussing the officer squad first and forcing it to retreat (getting rid of the aura buffs) is a big enough reward. If the unit is allowed to vet up with the aura scaling along, it could be brought back at vet2 or 3 perhaps.
Agreed on emergency repairs. Either needs to repair crits instantly or it needs to become a passive repair ability.
I'd rather have the Panzer Commander stay the same price but getting some better buffs. Especially sight range. The arty barrage could stay the way it is, but it needs to deploy much quicker.
Unlike the Brits, it would need to be a viable alternative to the pintle mounted MG.
