Buff Rangers because they are very expensive, they have only grenade, compared to paratroopers they are nothing, just look at Wehrmacht panzergrenadire, they have instant STGs and Uber grenade and they are buffed when they are around any german tank. May be give them smoke grenade and special ability or instant thompsons. Riflemen squad give them faster socket grenade like grenadiers they have istant panzerfaust. pershing is trash tank witch is to expensive and loosing with Panther in 1 vs 1 fight. Also Wehrmacht can make MG42 in the first building whinch instant pinches down units. And why Germans can make cheap infantry with submachine guns at the begening and USF and USSR cant?
