Operation Bolero Operation Bolero was the commonly used reference for the code name of the United States military troop buildup in the United Kingdom during World War II in preparation for the initial cross-channel invasion plan known as Operation Roundup, to be implemented in mid-1943, or for its lesser contingency alternative, Operation Sledgehammer, to be executed in the fall of 1942 in the event of German setbacks or to ease Axis pressure on the Eastern Front. ("Bolero" was the code name used in official communications to stand in for "United Kingdom" when describing the theater or movements.) What later became the Bolero plan – the buildup of a strategic air force in Great Britain in preparation for Roundup – was first submitted by Commanding General of the U.S. Army Air Forces, Henry H. Arnold, to General George Marshall, the U.S. Army Chief of Staff, on April 12, 1942, and set in motion a huge movement of men and material that laid the groundwork for Operation Overlord.

Operation Quicksilver (deception plan) Operation Quicksilver was a Second World War military deception. Undertaken by the Allies in 1944, the operation threatened an invasion of France in the Pas de Calais region through the simulation of a large Field Army in South East England. Quicksilver formed part of the Operation Fortitude deception, itself part of the strategic Operation Bodyguard plan. The key element of Quicksilver was the creation in German minds that "First United States Army Group" (FUSAG) commanded by General George Patton supposedly would land in the Pas-de-Calais for the major invasion of Europe, after the landings in Normandy had lured the German defenders to that front. (FUSAG was a genuine army group headquarters which later became Omar Bradley's 12th Army Group, but was given a fictitious role and many non-existent divisions for purposes of deception.)

Operation Fustian Operation Fustian was an airborne forces operation undertaken during the Allied invasion of Sicily in July 1943 in the Second World War. The operation was carried out by Brigadier Gerald Lathbury's 1st Parachute Brigade, part of the British 1st Airborne Division. Their objective was the Primosole Bridge across the Simeto River. The intention was for the brigade, with glider-borne forces in support, to land on both sides of the river. They would then capture the bridge and secure the surrounding area until relieved by the advance of British XIII Corps, which had landed on the south eastern coast three days previously. Because the bridge was the only crossing on the river and would give the British Eighth Army access to the Catania plain, its capture was expected to speed the advance and lead to the defeat of the Axis forces in Sicily.

818th Tank Destroyer Battalion The 818th Tank Destroyer Battalion was a tank destroyer battalion of the United States Army active during World War II. It first saw combat in July 1944, when it deployed into the Normandy beachhead in preparation for the breakout into France by Lieutenant General George Patton's Third Army. Working closely with the 5th Infantry Division, it moved through northern France up to the Moselle region, where it was involved in the Battle for Metz through September, October and November. In December, it disengaged from defensive positions along the German border and was moved north to fight in the Battle of the Bulge with the 26th Infantry Division. After securing the Allied flanks and mopping up the Bulge, it refitted for two months before fighting south along the Siegfried Line and crossing the Rhine in March. In April and early May, it rushed through southern Germany into Austria and Czechoslovakia, where it ended the war. After a brief spell of occupation duties, it was returned to the United States and disbanded in November. During the European campaign, the battalion lost a total twenty-six men and eight tank destroyers in combat.
