Mediterranean Theater of Operations in the context of "455th Air Expeditionary Wing"

The term Tactical Air Force was used by the air forces of the British Commonwealth during the later stages of World War II, for formations of more than one fighter group. A tactical air force was intended to achieve air supremacy and perform ground attack missions.

Unlike the numbered air forces of the United States Army Air Forces (USAAF), the Tactical Air Forces did not include strategic bombing/heavy bomber capability. The USAAF situation changed in late 1943 when the Twelfth Air Force transferred its heavy bombers to the newly formed Fifteenth Air Force. Later, when the Allied air forces in the MTO were reorganized into the Mediterranean Allied Air Forces (MAAF), the US 12th Air Force and the RAF Desert Air Force became part of the Mediterranean Allied Tactical Air Force and the US 15th Air Force and No. 205 Group RAF became part of the Mediterranean Allied Strategic Air Force. A Mediterranean Allied Coastal Air Force was also part of MAAF.

The European Theater of Operations, United States Army (ETOUSA) was a theater of Operations responsible for directing United States Army operations throughout the European theatre of World War II, from 1942 to 1945. It commanded Army Ground Forces (AGF), United States Army Air Forces (USAAF), and Army Service Forces (ASF) operations north of Italy and the Mediterranean coast. It was bordered to the south by the North African Theater of Operations, United States Army (NATOUSA), which later became the Mediterranean Theater of Operations, United States Army (MTOUSA).

The term theater of operations was defined in the US Army field manuals as the land and sea areas to be invaded or defended, including areas necessary for administrative activities incident to the military operations. In accordance with the experience of World War I, it was usually conceived of as a large land mass over which continuous operations would take place and was divided into two chief areas-the combat zone, or the area of active fighting, and the Communications Zone, or area required for administration of the theater. As the armies advanced, both these zones and the areas into which they were divided would shift forward to new geographic areas of control.

George Smith Patton Jr. (11 November 1885 – 21 December 1945) was a general in the United States Army who commanded the Seventh Army in the Mediterranean Theater of World War II, then the Third Army in France and Germany after the Allied invasion of Normandy in June 1944.

Born in 1885, Patton attended the Virginia Military Institute and the United States Military Academy at West Point. He studied fencing and designed the M1913 Cavalry Saber, more commonly known as the "Patton Saber." He competed in the modern pentathlon at the 1912 Summer Olympics in Stockholm, Sweden, finishing in fifth place. Patton entered combat during the Pancho Villa Expedition of 1916, the United States' first military action using motor vehicles. He fought in World War I as part of the new United States Tank Corps of the American Expeditionary Forces: he commanded the U.S. tank school in France, then led tanks into combat and was wounded near the end of the war. In the interwar period, Patton became a central figure in the development of the army's armored warfare doctrine, serving in numerous staff positions throughout the country. At the United States' entry into World War II, he commanded the 2nd Armored Division.

The Seventh Army was a United States army created during World War II that evolved into the United States Army Europe (USAREUR) during the 1950s and 1960s. It served in North Africa and Italy in the Mediterranean Theater of Operations and France and Germany in the European Theater between 1942 and 1945.

Originally the I Armored Corps under command of Lieutenant General George S. Patton, it made landfall at Morocco during Operation Torch as the Western Task Force, the first all-U.S. force to enter the European war. Following successful defeat of the Wehrmacht under Field Marshal Erwin Rommel in North Africa, the I Armored Corps was redesignated the Seventh Army on 10 July 1943 while at sea en route to the Allied invasion of Sicily as the spearhead of Operation Husky.
