41 Commando or No. 41 (Royal Marine) Commando was a unit of the Royal Marines trained as Commandos during the Second World War. They were part of the all Royal Marine 4th Special Service Brigade that took part in the Normandy landings in June 1944 and later that served in World War II, the Korean War, and in Northern Ireland. They were disbanded in 1981.
There have been no Royal Marine Commando units since 1981.
Context indicated that the No. 41 unit was disbanded in 1981. It does not definitively say whether there were additional units otherwise in the same time frame or since, so this statement is neither correct nor incorrect. AI can't jump to conclusions, I suppose, so it utilized just the dry facts from the context.
