About the assault-officer - if it moved from doctrine in the basic structure of the OKW units only one unit on the battlefield.
Its task is to strengthen the OKW infantry at an early stage and to maintain its survivability under enemy fire.
I watched a lot of games against OKW USA and the USSR - against rifles OKW volksgrenadier even as some, but against the Maxim gun+ recruits they are inferior even with the assault engineers.
The main reason for the construction of 6-7 units of volksgrenadiers is an attempt to repel the attacks and to hold the territory. Due to the number of rifles.
Let's look at the recruits of the red army - doctrines allow them to issue PPSH-41 - giving them DPS and survivability at the expense of the number of soldiers in the unit.
-What do you replace this doctrinal unit call-in with if it's taken from a commander and made into core army?
-Numbers is the reason why Volksgrenadiers are used in quantity, for short-ranged jobs you train Sturmpioniers. Where do they factor into this step? Sturmpioniers for their part are pretty good at the short-ranged job too.
-Conscript Ppsh-41 Kits don't improve close-range DPS but does not affect survivability or reduce the number of men in a squad. The only reason THAT idea works is because Soviets have zero non-doctrinal short-ranged infantry. And Shock Troops work much better due to grenades and armour, so the argument about Ppsh-1 upgrade is moot, it's actually one of the sh***ier upgrades.
STG-44 it's too big for volksgrenadiers. According to the version of the game - it recruits + a few veterans. So they need to upgrade the squad leader, as a 6 member group. And it needs to be armed with a good weapon, which corresponds to the unit - and this GW-43. Also there remains the problem of smoke and flame throwers for OKW as a fraction.
MP-40 will allow OKW to suppress spam tactics Maxim machine guns at the expense of call from the flanks and strong DPS in melee.
According to the text of the game. Which means jack sh** when you consider all the other unit/ bulletin/ ability descriptions that have similar errors.
Giving the "squad leader" a superior weapon does what exactly? One guy with G43 isn't going to make a difference, not unless you want the other unique attributes like sniping, in which case they turn from being too similar to Sturms to being too similar to Jaegers/ Panzerfusiliers ...which is what other people have already said.
Smoke and flamethrowers are another issue, and MP40s/ sergeant for Volksgrenadiers doesn't touch that. I recommend you make a separate thread on that.
