Here's a guess on the possible Germany --> Poland shuffle of US forces, based on the below hint.

According to Polish media reports, the United States could offer 2,000 soldiers to Poland, 1,000 more than initially agreed in June 2019. Those additional troops would include the U.S. Army V Corps from Kentucky and F-16s from Germany.
Another official with knowledge of the talks told Reuters that moving the V Corps to Poland was under discussion and that Poland could get more than the 1,000 troops agreed to last year, but would not say if 2,000 would be sent.
Disestablish the USAF F-16 squadron home based at Spangdahlem AB in Germany.
Germany maintains Spangdahlem ready to host deployments of stateside USAF or Air National Guard (ANG) F-15/16/35 's in a NATO contingency. Rotate smaller deployments of F-16's from stateside USAF &/or ANG squadrons to the Polish air bases at Poznan &/or Lash which are home base to Polish F-16's (for now, switching to F-35's in the future).
Locate in Poland the European portion of the US Army's newly re-established V Corps HQ (Ft Knox).
This would represent an overall increase of dedicated US combat power based on NATO soil. It's just pushing more of it closer to Russia & the E front, from Germany into Poland. Our legacy Cold War force disposition was still based on defending the Fulda Gap in Germany. This positions our forces to defend the Suwalky Gap in Poland. We're still treaty limited on the total number of forces we can permanently station in former Warsaw Pact nations so we increase the number of rotations of forces deployed (9 mos) from US based units.
