The Ukrainian Liberation Army was an umbrella organization created in 1943, providing collective name for all Ukrainian units serving with the German Army during World War II. A single formation by that name did not exist. The designation was used by Ukrainian nationalists in reference to a number of companies and local Ostbataillonen of Hiwi volunteers desiring to free their own territories from the Soviet rule. They included enlisted Ukrainian prisoners of war (POWs) of the Red Army. The core of the Liberation Army wearing the УВВ sleeve badge originated from the 14th Waffen Grenadier Division of the SS reorganized in April 1945 into the Ukrainian National Army (UNA) active until the German surrender in May 1945.
