Another thought. I think swapping those two STGs for 5 Mp40s would be a better change, and a relief against the Con-PPSH blobbing meta.
With this change they claim a new role, CQC. And not a part short range, part long range unit
A 5x MP40 upgrade would be a great addition to the OKW arsenal imo.
It would provide a decision between keeping a decent long/medium-range combat effectiveness for holding the line, or give you some firepower to assault a position. Reminds me of what Relic was thinking of when they thought up the Hammer and Anvil upgrades for the Brits.
