Still got bunkers and MGs.
And USF have fighting positions and hmg that easy accessible
I feel as though OST would have less trouble dealing with Ass engies, since-generally speaking an MG is almost always in their starting lineup.
And USF have T0 mortar that counter the T0 HMG.
If we are talking Support weapons-USF mortars have pretty bad range, strong--but barely used.
USF mortar is almost identical to the Ostheer one, especially give the different squad sizes.
In addition they have the pack howi that is very power even more so with white phosphorous (combine with critical kill weapon for extra fan)
the 50cal is locked behind T1, and the MG42 is just better at suppressing things in general.
And grenadiers are locked behind T1 that does not come with free bazooka squad.
the 57mm AT Gun vs the PAK 43 is honestly no competition, OST will win that one. (how it should be, if aligning with historical accuracy)
Actually plenty of competition especially given price episodically anything medium and bellow (if one uses AP rounds it counter mediums and AP )
But thats going off topic.
EDIT:
I've never once got the feeling of combined arms with OST, even when maining them. tbh-They've always relied on superior armor and defensive positions, I feel like their trade mark is their heavy armor and superior positioning.
Only that armor is not that superior.
Giving it as a vet bonus I tend to agree less with, unless the requirements are lowered. The idea of the 5th man is to have that extra early punch and giving it more survivability, there is no point in getting it later.
One particular argument i will always not agree with though, is "they perform better than strums". with risk of sounding sarcastic, I think thats the entire idea of call-in units. to outperform regular units.
Now compare them with assault grenadier that have the same price are doctrinal and CP 0 and you will find them OP
