4th Army

The 4th Army is a designation used by several nations throughout military history, notably by Germany, Russia, and the United Kingdom. In World War I, the German 4th Army played a key role on the Western Front, participating in the Battle of Ypres and other major offensives. During World War II, the Soviet 4th Army was involved in significant operations on the Eastern Front, including the defense against Operation Barbarossa and later in the liberation of Eastern Europe. The unit’s composition, structure, and operational focus have varied over time, but the 4th Army has consistently played important roles in some of the 20th century's most significant military campaigns.
