Kubel defeats even rifles at long range, providing rifles don´t have cover, same apply to echelons.
Volks beat rifles early game at long range, also stg is aptoinable than bars early one,
Jaegers are snipers, you have to put them behind main line infantry - volks and they will snipe models like mad,
3 volks and sturmpios will defeat 3 rifles and echelon in open fight if you cleverly use cover and range
Obersoldatens suck if you build them lategame but if you rush flakHQ and get 2 obersoldats and vet them, they will be crazy.
OKW isn´t played because how hard they get beated by current soviets and UKF lategame, these both factions are most played because they are strongest, USA is currently weakest amond all allied factions (oh the irony)
Volks in garrisons also destroy rifles until the smoke spam starts coming. Kubels bleed the shit out of infantry for 0 bleed of their own.
