US support weapon squad members still drop like flies, you are better off stealing an MG from the Germand and using handheld AT most of the time, at least in my experience.
Also the Riflemen vs Volks combat often comes to RNG and the use of cover so I don't see how it is strong as ever.
1) The most important change to USF support weapons was the introduction of the mortar that allows riflemen to stay in cover and have indirect support. Other than that:
57mm ATG
Penetration from 140/125/115 to 150/140/130
Accuracy changed from 0.05/0.0425/0.03 to 0.055/0.05/0.04
M2HB HMG Team
M2HB .50cal HMG penetration from 3/2/1 to 7/6/5.
New Ability: Armored Piercing Rounds - Timed ability that loads AP rounds for 25% increased damage and +10 penetration.
2) Riflemen received no nerf, the introduction of the ST44 for Volks is another mistake and I have explain why in a earlier post(see page 2 point 2). So USF support weapon and direct fire support (USF's Achilles tendon) got massively buffed (captain arty,M8 )yet their strong point riflemen received no nerfs.
