the best ways to use US Army against Russia

[Lampshade111]

Fighting Russian first-elchelon units eh?

Well first while the M1A2 Abrams some of the equipment of the T-90A (VIRSS, gun launched ATGMs, etc.) the later APFSDS ammo should have no problem dealing with the T-90A. Also the M1A2 SEP is very well protected when in a hull down position. In fact I don't think the T-90A can penetrate the front turret in WINSPMBT, so try to use this advantage when possible and get your tanks in a hull down position.

WINSPMBT's rendition of the countermeasures system the T-90A has isn't entirely realistic, but regardless VIRSS has a chance to block your Bradley's TOW-2 missiles. While it seems the Russians only have Arena on a few prototypes in real life, in the game they may end up with some tanks with CIWS systems, these have a better chance to stop your missiles. TOW-2B should be able to penetrate Russian armor from any angle as it is top-attack but with older model TOWs you may need to hit the sides. Javelin missiles used by your infantry are quite expensive, yet their effectiness seems rather inconsistent. In some battles I have crushed multiple tank platoons with them, in others half of them that hit don't penetrate.

If the AI buys a ton of older anti-aircraft guns like they sometimes do, use your artillery the best you can. Against mobile SAMs and advanced anti-aircraft systems, sending in a stealth aircraft or SEAD F-16, followed by lets say a F-15E loaded with JDAMs can be quite effective.

Helicopter effectiveness varies from map to map.
