[2] On 24 October 1917, Capello, who was ill with a fever at the time, failed to gain authorization to withdraw his forces; Cadorna had vetoed the request, although, 6 days later, he would eventually agree and gave orders to retreat past the Tagliamento River, Capello's original requested location.

[3] During World War II the 2nd Army was the Italian (Complex Major) Great Unit charged, from 1940 to 1943, of the activities of control and garrison of the occupied or annexed territories of the former Kingdom of Yugoslavia.

The 2nd Army was a second line force with most of the men in their late 30s and early 40s, the only really largely combat ready and effective (Simple Major) Great Unit was the assigned component of the Alpine Division Julia only partially deployed in the yugoslav theatre of operations as a whole unit.

In October 1942, the 2nd Army helped execute Operation Alfa, along with supporting Chetnik forces.

Other parts of the 2nd Army also keep fighting against the Germans along with the Yugoslav partisans in Division Italia (Yugoslavia), during 1944–1945.
