If you replay is direct to me my point is that the Ostheer officer should be easier to vet.
That can be achieved either from shared vetrancy or/from weapon upgrade (or a faust).
Other than I agree this units should add via utility and not via direct combat.
The barrage is rather lucking especially compared to the stock Major barrage that does not require an arty unit to be present.
Maybe the unit to could be improve its utility by having an aura that affect only arty units like mortars, weffers and Lefh maybe shortening barrage or increasing barrage range accuracy. The officer then could share experience with these units.
I was referring to stefenbk1´s post about his usage of the artillery officer. But you have some good points.
What I would like to see are some good abilities. The idea of an aura only for indirect fire units sounds good, but rather boring. I would suggest a supervise ability (like us captain) only for mortars panzerwerfers and leigs, with various buffs to reload speed, accuracy and barrage cooldown. Additionally the officer should get an actual arty (like the major).
My idea behind this is, to have two playstyles, one more focussed on stationary arty support suited the lefh commander and the other one focussed around mobile support with combat bonuses, so you can skip t1 with Osttruppen commander and still have a form of artillery. Then get rid of the vet 1 medkit and the coordinated barrage ability and replace them with a new one. My idea would be a sort of kubel recon mode, where it detects artillery units in the fog of war within a radius. It would have a small munition cost and last about 30 secs. This ability would suit the theme of artillery commander and it would be useful in counter barraging or hunting down katyushas in the late game. The abilities should also scale with veterancy so giving him shared veterancy isn´t a bad idea.
This are my suggestions for a complete overhaul of the officer and in my opinion, it would make him a lot better. So what do you think?
