7th Army (Kingdom of Yugoslavia)
The 7th Army was a Royal Yugoslav Army formation raised prior to the German-led Axis invasion of Yugoslavia in April 1941, during World War II. It consisted of two divisions, two brigade-strength mountain detachments, and a brigade-strength infantry detachment. It formed part of the 1st Army Group, and was responsible for the defence of Yugoslavia's north-western frontier with Italy and Germany. Like all Yugoslav formations at the time, the 7th Army had serious deficiencies in both mobility and firepower.

1st Army Group (Kingdom of Yugoslavia)
The 1st Army Group was a Royal Yugoslav Army formation mobilised prior to the German-led Axis invasion of Yugoslavia in April 1941 during World War II. It consisted of the 4th Army, 7th Army, and the 1st Cavalry Division, which was the army group reserve. It was responsible for the defence of northwestern Yugoslavia, with the 4th Army defending the eastern sector along the Yugoslav–Hungarian border, and the 7th Army defending the western sector along the borders with Germany and Italy. Like all Yugoslav formations at the time, the 1st Army Group had serious deficiencies in both mobility and firepower as well as internal friction among the different ethnic groups, particularly between Serbs and Croats.
