instant suppression? no.
faster reposition on vet? yes.
I believe allies infantry on vet also gain less suppression.
Allies already have good arty to clear weapon teams.
Why allies MG keeps get tiny buff. But wehr no? Dont forget grens are bad at flanking and clearing weapon teams, at least compared to what stock allies have.
Also not just MG, but mortar and pak too. A little faster on vet, either buff teardown or setup. Wehr imo has poor veterancy gains or at least not complimenting their flavor.
1. The only Mg come at the same time with Mg42 is Viker and compare to vicker, mg42 have better tear down/setup time (cant find the stat but i say on experience in game). Other two stock Mg of allies is maxim and M2. While both m2 and maxim reposition faster than 42, they both have narrower arc and cost fuel to unlock.
2. As i understand, "Allies MG" that keep getting buff by your means is vicker and maxim in next patch. For the vicker, it get buff because infantry sections got neft, for the maxim, it get buff because mod team finally found out that it is bad.
3. Gren are bad at flanking because it is their design - long range specialist fighting from static positions. To deal with weapon teams, ost have an unit called GWR 34 mortar squad. In case you never head about that unit, they sit in T2.
4. Both Gwr 34 and park 40 have useful vet 1 abilities (counter battery will get buf f next patch) and gren will event have a dmg reduction modifier next patch so you can, and should stop that "ost have bad vet".
