Recently, NATO has decided to reinforce its eastern flank. In addition to the four battlegroups already stationed in Poland and the Baltic States, four new battlegroups are now being added. The four new NATO battlegroups will be stationed in Romania, Bulgaria, Slovakia and Hungary. With these additional reinforcements, roughly 25,000 NATO soldiers will be present in Eastern Europe. The countries themselves provide about 290,000 soldiers. On land, the reinforcements serve mainly as deterrence for Russia, to show the Russians that invading any of these countries will have massive consequences.
