The Polish First Army (, 1 AWP for short, also known as Berling's Army) was an army unit of the Polish Armed Forces in the East. It was formed in the Soviet Union in 1944, from the previously existing Polish I Corps in the Soviet Union, as part of the People's Army of Poland (LWP). The First Army fought westward, subordinated to the Soviet 1st Belorussian Front, during the offensive against Nazi Germany that led to the capture of Warsaw in January 1945, and the capture of Berlin in May 1945.
