USF basic infantry (riflemen) vet scales them like all other basic infantry, and like all other basic infantry they are dependent on weapon upgrades to truly shine late game. 1919 rifles are extremely potent and BAR rifles are nothing to sneeze at either.
Except the 1919 is doctrinal. The BAR is indeed good; not LMG42 good but not a waste of Muni; Bazooka may actually be more interesting with (effectively) reduced cost.
The Vet-scaling just plain wrong. I'd have to look it up but its not good enough to compete with Grenadiers of either flavor. Also the Conscript exists which immiedately makes the "all other" argument wrong.
All mediums have "paper thing" armor with the exception of the Vet 2 PIV (or OKW PIV) and the Easy Eight. USF just has the lions share of medium tanks. With heavies being limited to one you might have noticed that all basic AT guns have extremely low bounce chances on even the non-paper thin armor tanks.
Ironically the faction hurt most by this is Ostheer; who's mediums hit the field dead last which means you need to tie vet 0 PIV's against a LOT of AT.
It doesn't help that this is the only tank class they can use at the moment (Non-Alpha testers don't get excited)
This may be more a symptom of AT being hilariously easily available for frankly anyone to get a hold of; a lot of larger sized games I'll see Soviet players take SU85s for the focused-sight, and keep around a legion of SU76's. I'm not really sure what would fix that without rendering the SU76 a potato again; aside from making the other AT options more attractive, but that opens up a whole new bag of problems.
All USF and OKW crews should have 5 men IMO, and Iv never liked the received accuracy on MG teams but w/e at least when you recrew you don't get that anymore (which means para dropped weapons when recrewed are more durable)
YARP.
Depends, USF blobs with barfinder/para spam is brutally OP against OKW who lacks any kind of late game suppression platform. But yeah in general USF is not OP.
Having played against Paraspam; yeah really annoying.
Micro is not a catch all term. OKW relies on microing a lot of infantry units aggressively and baby sitting a small amount of tanks. Soviets rely on microing a coordination of artillery/support weapons for area denial while playing aggressively with armor. USF relies on extremely aggressive infantry play while remaining mobile with armor support. Ostheer relies almost entirely on support weapon micro while using tanks to support defensive emplacements or flank attacking enemy forces.
One upon a time USF required the most micro, but since all factions now are stuck having to use lots of mediums I wouldn't say that's the case.
I'll admit now I haven't played 1v1 in a very long time (and it was hard to find a game at the time), but reading the words "OKW" "Microing" and "infantry" in that order does not seem to happen. That is to not say its not punished hilariously fast by Scotts, SU76s, Pak-Howis and lucky Zis's (or good Shock-troop play). Annoyingly this blob comes back pretty fast if the med-truck is set up in a good spot, so you will basically attrition them down if they're not capable of renewing forces quickly (although again, ZSU-Quad makes it hilariously easy for soviets; still not sure why its 270MP). That was less a jab at OKW and more at people just attack-moving.
USF trades durability for extremely high offensive power. That's it's "gimmick". Relic decided to reduce OKW's gimmicks, now it seems like they will next start focusing on USF if their streams are any indication.
Probably true; early offensive power isn't actually all that great early game compared to dumping a Kubel at cut off and giving the other guy the finger while STURMPIONEERSGUNJAMGUNJAM move past suppressed units like a cop spraying protesters with mace. Faster access to the fun-stuff does help them out alot but its more highlighting what the actual unit problems are.
