BRIXMIS (The British Commander-In-Chief's Mission to the Group Soviet Forces of Occupation in Germany) is one of the most little-known and covert elite units of the British Army. They were dropped in behind 'enemy lines' ten months after the Second World War had ended and remained operation their intelligence-gathering missions until the fall of the Berlin Wall in November 1989. During the period Berlin was a hotbed of spying between East and West. BRIXMIS was established as a legitimate channel of communcation between the Red Army and the British Army on the Rhine, they were trusted by the Russians. Its 'clean status' made BRIXMIS a key part of the Cold War. However, their missions were covert and they acted behind the shadows to steal advanced Soviet equipment and penetrate top-secret training areas. Their vehicles and equipment have continued to hold fascination for military history and vehicle enthusiasts. This unique history of this most elite of units offers a new understanding of the British role in the Cold War.
