U.S. claims that an invasion is immanent and has long called for U.S. citizens to evacuate the country. The reporting on the Ukrainian side is that the U.S. is attempting to fear monger and that the threat of invasion is overblown. I'd side with the U.S. in their assessment, Russian aggression will not be curbed with diplomacy, and all diplomatic efforts have failed. Whatever Putin wants, he'll get it.
Polan is also expanding its army personal armored tank and other strategic weapons. Source link. They are doing this to checkmate Russia. It seems Putin is in a very bad position and looking for a way to get out of this mess. The Polish army creates a simulation war with Russia and finds out how vulnerable their military might be. Strength Ukraine and Poland's arms force will strengthen NATO power in the region.
If there is no Plan of NATO to assist Ukraine in case of Russian invasion then why it is being reinforced? Media is predicting war since past 3 month and panicking everybody but Russia has its own limits & logics , Putin simply wants to keep NATO far away from its neighborhood as no country even USA doesn't want any hostile forces near its borders , there is very slim chances of full scale war because the world economy is already in serious trouble because of coid-19 and it can not afford any further damage.
