This is the current DPS profiles
Notice that Mp44 continues become better with range and eventually become better than PPsh, making it extremely difficult to properly position the shock troops.
This could be the suggested DPS profiles

Note that Mp44 stop improving bellow the range 7 while the PPsh continues to improve thus Shock gain an advantage as the close in up to range 5.
DPS is per weapon not squad and thus the DPS of the shocks at range 10 should about equal with SP squad.
Also not the steep drop of the Mp44 DPS beyond 17 giving some ranges for semi automatic to be relatively more effective.
