蘇聯紅軍跟英美聯軍不在一個戰場， 無需協同。
Supreme Headquarters Allied Expeditionary Force (SHAEF; /??e?f/ SHAYF) was the headquarters of the Commander of Allied forces in northwest Europe, from late 1943 until the end of World War II. US General Dwight D. Eisenhower was the commander in SHAEF throughout its existence. The position itself shares a common lineage with Supreme Allied Commander Europe and Atlantic, but they are different titles.
