Which major operation did the Royal Marines participate in during 1982?

The Royal Marines participated in the Falklands War in 1982, a significant military conflict between the United Kingdom and Argentina over the disputed Falkland Islands. This war showcased the Royal Marines' expertise in amphibious operations, which allowed them to execute complex landings and secure territory under challenging conditions.

During the Falklands War, the Royal Marines were crucial in various operations, including land assaults and securing strategic locations. Their training and adaptability in hostile environments played a vital role in the success of British forces, demonstrating their capability in combat scenarios far from home.

The other options, such as the Gulf War and the Iraq War, occurred later, while the Korean War took place much earlier, in the early 1950s. Thus, these conflicts are not associated with the Royal Marines' involvement in 1982.
