The United States Marine Corps can trace its beginnings back to the early British Royal Marines. The Marines has in its USMC Emblem details modeled from the Royal Marine Corps, and it does not have in its logo a defensive shield like many of the other services. November 10th 1775 is the birthday of the United States Marine Corps. They were created by a committee of the Continental Congress, to create a new stern unit of the military, called the Continental Marines. They operated at the direction of the Continental Congress until 1798 when President John Adams signed a bill officially created the United States Marines.
The Marine Corps are considered by many to be the toughest of the Services in the United States Armed Forces. Since its very beginnings the Marines have been infantry forces that have served aboard Navy vessels. They are the rapid response soldiers of the United States Military. The U.S. Marine Corps have participated in every single conflict since the formation of the United States, beginning with the Revolutionary War, up to and including the current Iraqi War against Terrorism and the Afghanistan War.
The United States Marine Corps has been since the inception based largely on board ship, to be able to respond swiftly to any battle requirements either at sea or on land. Marines are known to have written the book on infantry and amphibious landings, and bravery in battlefield operations. The role of the Marine Corps has expanded as it began to focus on infantry missions and battle tactics on land. The Marine Corps codified the combat duties using the Advanced Base mission doctrine detailing the use of Marine Corps Infantry soldiers in seizing bases and battlefront operations. They also developed techniques and tactics in defending and seizing coastlines during World War II.
The United States Marine Corps have become the rapid response amphibious response arm of the United States Military. Of the four services in the Department of Defense, the Marine Corps is the smallest, but mighty in its own right. It serves to develop technique, tactics and equipment for amphibious landing forces, to provide for the defense, or offensive seizure of naval bases and other operations on land to support naval campaigns and any other duties that the Commander in Chief, the President of the United States may direct.
