After reforming and retitling, the unit transitioned to the Commando role as a formed unit, by-passing the individual volunteer and selection process undertaken by Army Commando candidates. Personnel undertook, and completed, the Commando Basic Training Course at Achnacarry, Scotland. As part of the 1st Special Service Brigade, the Commando participated in Operation Overlord (the D-Day Normandy landings), before going on to move through Europe into Germany, including Montforterbeek on 23 January 1945.[3] During the Ardennes Offensive, the retitled 1st Commando Brigade was given the task of holding a stretch of the River Meuse; it was during this period of operations that Lance Corporal H. Harden, a medical orderly of the RAMC attached to 45 (RM) Commando, won the Victoria Cross
