Both Sturm officer, J command and commais come at CP 2 not CP 0.5. The strum officer start with rifles and pistol so does the commissar...One builds the S.O or Commissar for their utility not their DPS.
Actually the only thing UKF needs is utility they have lost of damage. What they lack basic tools like early anti-garisson.
Rushing the officer is pointless vipper. Vet0 it struggles vs sturms depending on approach. And gets handily beaten by pgrens. It's a unit you invest in for flanks and to provide some CQB power mid and late game when it vets up.
I don't understand the claims if "hero unit" at all. If you're going to put forward an argument why the officer is OP for timing maybe you should look at the timing of pgrens or penals as well. Because pgrens especially are stronger out the gate.
Your argument to buff royal engineers instead has already been attempted, it turns out having cheap spamable engineers that could double as strong CQB units out trading StG axis infantry was OP and impossible to balance and they were hit by RA, dps and vet nerfs.
Surely it makes much more sense to have the officer at a premium price point to provide unit variety to a stale UKF roster and as a easy to balance CQB unit that's only role is that outside of recon and on me (which could use some minor changes, maybe recon with tech).
