The closest thing I know of at this point was the deployment of Mexican military forces in recovery efforts shortly after Hurricane Katrina hit.

They had been issued US type BDU uniforms and enough interpreters to be virtually indistinguishable from US troops at the time, and their presence was not widely known until afterwards, in part when their vehicles were recognized as not being US vehicles and were seen in a Mex military parade.

The best information we have is that they were involved in food and water distribution operations along with assisting in evacuating people from flooded areas, primarily using their amphibious vehicles which are smaller and more maneuverable than the LAV. There is no recorded incident of them being involved with gun confiscation.

As an added note, even National Guard involvement in the gun grabbing was apparently limited to reporting armed individuals to law enforcement, who then confronted and disarmed armed individuals. SWAT teams from other parts of the US did participate in gun confiscation.

We do have a fair amount of Russian and other east European immigrants with prior military service entering the US military, but realize that those with experience in the Soviet/Afghanistan war are at this point overage for most enlistment and officer programs.

The Russians can often learn English well enough that they are not readily distinguishable from Americans, although they are rarely going to be dark black (they have "black" mixed race people quite often with blue or gray eyes) but they do have several (Cossacks) who can readily pass for "Mexican" or maybe even "Indian".

I have seen Portland police talking in Russian on cell phones, and some of their recruitment literature which fast tracks immigrants, but that can't be readily done on a volume that would make true martial law possible.

If modern Russian military were to conduct exercises in the US, that would be limited to probably nothing larger than Battalion size units being put at the larger US bases.

As for any level of resistance to Russian forces on "peacekeeping missions" well, heh heh heh. I suspect that someone is telling the story to "make" some news.

If it were to happen (and I think it is in reality unlikely) they would be outfitted to appear as US forces. If they were to show up with their own gear and toys, well, you can imagine how we would be stocking the tables at the gun shows in the free zones after the feds finish shutting down Colt, Ruger and S&W....
