The idea of giving Conscripts a single DP-28 was brought up before. Miragefla and Mr. Smith turned the idea down, because then we would have DP-28 Conscript blobs that are essentially just as lethal as any LMG42 Grenadier, LMG34 Obersoldaten, M1919A6 Riflemen, or M1919A6 Paratrooper blob (just use quantity to overcome quality) but more durable, have a Molotov, have an AT snare, cheap to reinforce, and can Oorah away from or around HMGs.
I would argue that the LMG42 upgrade for Osttruppen is acceptable because they receive a 50% accuracy penalty outside cover, making it worse than a single DP-28 outside of cover.
I don't think the lmg42 is unacceptable at all for ostroppen and is a welcome change, but I maintain that DP28 cons would simply be worse off ostroppen. You could indeed have molitovs and at nades, at further additional cost (again, cost effeciency..) and oorah does certainly remain a trait, one that's counter intuitive to a stationary long range focused weapon, but a trait nonless...
It would almost be better off if OORAH increased ROF of their mosins than getting a weapon uograde. Similar effect but maintain their uniqueness.
As a matter of fact they could have scaling built into oorah tied to tech. Increased ROF when stationary, longer duration, reduce target size slightly... Reduced cooldown when active... All at the cost of frequent munitions drain. Nothing over the top, but small things that only last duration of oorah and make cons at least decent at the time.
There's Soviet munition sink then as well.
