What's the difference between the navy, the army, and the marines?

Question

i only know that they all involve the war and that the marines are on water...

Answer 1

Navy :

A nation's entire military organization for sea warfare and defense, including vessels, personnel, and shore establishments.

Marine:

military corps that forms a separate service within the U.S. Dept. of the Navy. The commandant of the Marine Corps is a member of the Joint Chiefs of Staff. During conflicts, the Corps is charged with conducting all land operations essential to the successful prosecution of a naval campaign (see marines); during peacetime, its top priority is combat readiness. Famous for its esprit de corps, the Corps emphasizes physical fitness and intensive training. In 1775, the Continental Congress created two federal battalions of marines to serve as naval infantry. In 1798, the United States Marine Corps was established and placed under the control of the Secretary of the Navy. Marines have participated in every major war, especially the Mexican War; World War I; World War II; the Korean War; and the Vietnam War. They have developed expertise in counterinsurgency and guerrilla warfare, as well as in commando operations and amphibious warfare. Marine units are self-sufficient, with their own tanks and other armor, artillery, and air forces.

Army

Armies changed technologically as well. Trench warfare resulted from improvements in small arms and prompted the development of various weapons designed to end the stalemates and murderous battles that entrenched forces produced. The growing role of artillery made logistics even more important. From the first, armies had needed soldiers to supply the fighting troops–even when the armies simply lived off the land. No formal distinction orginally was made between service troops and combat troops, but with the creation of the great citizen armies after the French Revolution formal specialization proliferated, and quartermasters, ordnance troops, engineers, and medical specialists were organized into separate units. The development of mechanized warfare in the 20th cent. made armies powerful and highly mobile and yet did not always provide them with the capabilities needed to fight so-called asymmetric opponents, such as they face in guerrilla warfare and terrorism.

The term army is still applied to all the armed land forces of a nation, but it is also used to designate a self-contained unit with its own service and supply personnel. In many armies today the division (usually about 15,000 men and women) is the smallest self-contained unit (having its own service and supply personnel). Two or more divisions generally form a corps; and an army (c.100,000 men or more) is two or more corps. In World War II, army groups were created, including several armies (sometimes from different allied forces). Above the groups is the command of a theater of operations, which in the United States is under the control of the Joint Chiefs of Staff.

Answer 2

Army - Land based but also use rotary wing combat aircraft (helicoptors)

Navy - Sea based combat force

Air Force - Air based combat force

Coast Guard - protect our coastlines, water based force

Marines - sorry, but they are not a Department, they are a part of the Navy. They are the Navy's land combat force.

All Departments (Army, Navy, Air Force) have elements able to operate simular to the other departments, but not exaclty.

The reason you hear Army Navy Air Force is because the Army was started first, then the Navy and the Air Force came last.

Answer 3

Marines are the BEST of all Armed Forces. They fight first and last to leave. They fight on land, in the air and sea. It's the toughest service to get into.

The army fights on land.

The Navy fights in water and is DoT to the Marines

Answer 4

navy - ship
marine- the best of the best, ground air above all
army- ground troops
I prefer the marines, cause they just own..

Answer 5

" Marines" is always capitalized and are first to fight--on land. I can't nor won't speak for the others except to say that if you join one of the others, you will have to go through life wondering if you could have ever made it in the Marines.

It could be a heavy burden.

Answer 6

Army is land-based assault, ex troops on the ground.

Navy is sea-based assault, ex ships in the ocean.

Marines are amphibious assault, ex beach type troop landings. Also special forces for secret missions.

They are all great Americans.
