The USA/NATO don't always know best, think about it, the CIA though that "RPG" was an acronym for: "Rocket Propelled Grenade" It turns out that Russians speak Russian

and that "RPG" is "Anti-Tank Rocket" or something of the likes, however the media (I think US Army too) still calls them "Rocket Propelled Grenades"
The U.S. Army may know of its capabilities but it shapes up to be more than a match for any other wheeled "APC" armaments wise anyways. The "Kornet" ATGM is more deadly than anything the STANDARD Stryker carries. Luckily, Russia has little money and will not have enough to make a difference, it would take a lot of BTR-90s to do any damage to US infantry in Strykers if there was M1A2s supporting them (and there could be air-support as well).
