The marine corps has been in existence for more than two hundred years now and it all began with the formation of what was known as Continental Marines long back in the year 1775. Since its inception, this force has since been involved in all major military operations of the United States and currently stands at nearly two hundred thousand strong personnel, a size which is big enough to dwarf even the full armies of several nations, yet it is one of the smallest wings of the US defense forces. America has seen lots of ups and down since 1775, the year of inception of Continental Marines, and the USMC has been through thick and thin during various circumstances including the American civil war, First World War, Second World War, Korean war, Vietnam war, Gulf war, 9/11 attacks and so forth.
