Not in large groups. Individuals and detachments, however, very much so.

During the summer of 1941, the U.S. sent a detachment of Marines to Reykjavik, the capital of Iceland, to protect U.S. shipping interests (Outposts in the North Atlantic: Marines in the Defense of Iceland).

Most of the Operation Overlord invasion force comprised American, British and Canadian soldiers, Marines were part of the massive fleet off Normandy that supported it.

From 1942 to 1944, the Corps deployed leathernecks to the naval base in Londonberry, Northern Ireland, to help protect it from German attacks and sabotage attempts by militant members of the Irish Republican Army.

And after the war, their job of guarding locations would get kicked into overdrive, and given to a Marine Corps detachment.

I know personal experience is discouraged, but for the sake of conversation and to connect my last statement, my old English teacher once stated that her father, a Marine major, took her to the Eagle's Nest post-war, which was entirely guarded by Marines.

The Marines were purposely excluded from Europe during World War II and did not play major roles in the largest amphibious invasions in this country's history. Ironically, the Marine role in Europe was greater in World War I, where they received so much praise that the next generation of Generals maintained a grudge against the Marine Corps.

The censorship rules during World War I had outlawed printing the unit or individual names while reporting on frontline battles, which prevented a huge public following of any particular unit's achievements. However, a celebrity journalist name Floyd Gibbons got shot in the eye while covering the Marines, and his last hyperbolic and effusive dispatches were published uncensored. The dispatches made it sound like the Marines had single-handedly reversed the tide of the German onslaught of shock troops. Units could not be named, but referring to the "Marines" was not a unit designation and the USMC got a lot of great press. The general sentiment at home was that Marines were elite and better than regular soldiers, and the bravado of Floyd's exaggerated accounts became Marine dogma. Even the Marine Corp's nickname "devil dogs" was almost certainly based on an apocryphal nickname given by the Germans. The supposed Teufelhunden was not grammatically correct and no record existed of that term in the German language before it was invented by an English-speaking propagandist putting words together from a German dictionary.

In addition to the general desire of the Army to not share the European Theatre, the Marine high command had been foreseeing Japan as the principle enemy and had oriented itself accordingly.
