Many think of the United States Marine Corps as a second land army, and
while it has been employed in that capacity, it is foremost a naval
expeditionary force able to seize, secure, and defend advanced naval
bases in support of major campaigns.
The Corps dates back to the Revolutionary War, but while they served in
the conflicts of the 19th century, they are famed for their part in the
wars of the 20th century. On the Western Front in World War I they were
blooded at Belleau Wood. Between the wars the Corps developed amphibious
tactics which were employed to great effect during the Pacific island
campaigns during World War II including the infamous battles of Peleliu,
Iwo Jima and Okinawa. The names of the Corps is forever entwined with
the battles of Inchon and Chosin Reservoir in Korea, and Hue and Khe
Sanh in Vietnam. The US Marines have continued their expeditionary role
to this day, undertaking not only combat operations but also
peacekeeping, peace enforcement, humanitarian relief, and
short-notification/limited-duration contingency operations.
This concise history charts the evolution of the Corps as it has adapted
to changing combat over two centuries.
