A part of the US armed forces designed to operate on a very cost efficient basis, thus, operate outdated equipment and take more responsibility at a lower rank than other branches of the military in order to keep the pay of the Marines low; used mainly for initial attack and high risk operations rather than risking the loss of other branches which the government has spent more money in equipment and training on.
"The Marines did not take part in the Battle of Normandy, or D-day."
