I really enjoy playing Prostruppen with HMG spam into fast oswind, thanks to the supply drop. It work really well both against UKF and USF
Cant really speak out of 1v1 experience, but isn't Osttruppen usually a horrible idea vs USF? Riflemen with BARs and/or grenades are too mobile and just melt through Osttruppen. Yeh you usually have an HMG42 next to your Osttruppen, but how u wanna protect it from flanks or when it needs to re-locate after a USF smoke nade?
Osttruppen cant really cut it in these situations vs riflemen imo
