Royal Marines and US commandos blast their way through a state-of-the-art training site in Scotland this week.
The two-week exercise consisted of mountain training in Inverness, which included navigation and survival training and climbing Ben Nevis.
Both British and US units are charged with protecting high value naval establishments and assets – in particular the nuclear deterrent.
Exercise Tartan Eagle has taken place since 1994, a joint training operation between British and American forces, staged both in the United States and Scotland.
According to a 2009 U.S. military news release, exercises “included weapons ranges, convoy operations, anti-ambush strategies and navigational classes, as well as a cultural trip to the National Museum of the Marine Corps” in Virginia.
