I am perfectly aware of that but with the USF tech changes there is little reason for non vetted AP rounds for these HMG. It can be moved to vet 1 and be consistent with axis hmgs.
If you want consistency with axis mgs i expect
1. Ap rounds doubling dps
2. Near instant suppression for the maxim and vickers
3. Access to the kraut teleportation device for the 50 cal maxim and dshk/remove deathloop-The maxim/dshk made 4 man
4. Massively increased arc of fire
I can imagine the axis tears if an mg with mg42 suppression arc and timing were to exist on the allied side
