The 7th Army was formed during several periods in World War II but always held in reserve. It saw little action. The 7th Army was first formed between September and December 1939, and later between June and October 1940, in reserve for the Italian invasion of France.
In September 1941 it was again formed, to defend Southern Italy (Apulia, Campania, Lazio and Calabria).
In September 1943, after the Armistice of Cassibile, they offered little resistance to the Allied invasion of Italy and surrendered to the Germans.
