What happened to US troops and equipment in turncoat nations?

I don't know. It's not a like-for-like comparison, but Spain did kind of knuckle under after the Madrid train bombings and, by comparison to a T2K type scenario, the casualties were minimal and the enemy not nearly as dangerous. It's not beyond the realm of comprehension for the Cold War Spanish government to respond to a nuclear bloody nose by bowing out of the war.

I don't see U.S. forces being pulled from formerly allied nations that suddenly start putting out a lukewarm vibe. On the other hand, some "turncoat nations" might expel U.S. personnel prior to officially turning coats. I think what "turncoat nations" do with American personnel and materiel depends on the timing of their respective declared changes of heart. If it's after things go nuclear, I suspect they'd intern U.S. personnel, effectively turning them into hostages/human shields against a possible American nuclear response. Any American materiel would be "impounded" and eventually used. I don't have my v1.0 timeline in front of me at the moment, so I can't be more specific.
