The Sturmoffizier scales way better and at vet 5 (which is really easy to get with the shared vet) completely wipes the floor with a (vet 3) Commissar Squad. Or most other squads for that matter.
starting RA 0,91
Veterancy 3: +40% Accuracy
Veterancy 4: -29% Received Accuracy
Veterancy 5: -25% Weapon Cooldown, Offizier switches to an StG 44
VS strating RA 0,87
-Veterancy 2: +40% weapon accuracy. Increases Propaganda, Stand Your Ground, and Fight to the Death range by 5.
-Veterancy 3: -29% weapon cooldown, - 23% Received Accuracy.
yep totally better it gets 0,01 better RA at vet 5 and worse CD for weapons
the stg is useful but does not make up for the fact all its ability are worse and more expensive than others
+ it lacks in utility
and this does not excuse the poor performance early unlike other officer units
