British Forces Germany (BFG) was the generic name for the three services of the British Armed Forces, made up of service personnel, UK Civil Servants, and dependents, based in Germany. It was established following the Second World War, the largest parts of it becoming known as the British Army of the Rhine (BAOR) and RAF Germany (RAFG). Both components had the mission of defending West Germany and remained there for the rest of the Cold War.

I Corps was an army corps in existence as an active formation in the British Army for most of the 80 years from its creation in the First World War until the end of the Cold War, longer than any other corps. It had a short-lived precursor during the Waterloo Campaign. It served as the operational component of the British Army of the Rhine during the Cold War, and was tasked with defending West Germany.
