Why would I want Kar rifles on a unit when I can get stgs which are like rifles, but way better up close and on the move?
Not true. The Offizier scales way better than STG44 Volksgrenadiers, and it also gains veterancy much quicker (because of shared vet). Volks only gain a slight edge at vet 2, but the Offizier's DPS pulls ahead at vet 3 and at vet 5 it's nearly twice as high.
Remember, the Offizier's bodyguards have
Obersoldaten Kar 98Ks which are really powerful rifles. They are basically as good as Volks STG 44s at short to mid range and twice as good at long range.
Volks with STG 44 at range 10 have:
- 24.174 DPS at vet 0;
- roughly 35 DPS at vet 2;
- roughly 35 DPS at vet 5.
(Combat bonuses: 1.3 accuracy, 0.8 cooldown)
Sturm Offizier at range 10 has:
- 21.269 DPS at vet 0;
- 27.592 DPS at vet 2;
- roughly 55-60 DPS at vet 5.
(Combat bonuses: 1.4 accuracy, 0.75 cooldown, +1 Obers Kar 98k, 1x PGren STG44)
Furthermore, because of the severe burst duration multiplier (0.375), the moving DPS for Volks STG 44 is not better (roughly 45% at range 10) at close and mid ranges than rifles (roughly 45% at range 10 for most rifles, 50% for Obers Kar 98Ks).
In conclusion, the Offizier is basically a cheap Obersoldaten squad that trades an LMG 34 for an STG 44 and powerful abilities. Besides these very useful abilities (smoke/forced retreat vs HMGs, forced retreat vs elite squads or focus fire to melt specific squads) the unit's DPS at vet 5 is high enough to quite easily win versus anything that isn't an elite squad (even vet 3 double BAR Rifles have only ~40 DPS at range 10).
