20+ Differences Between Army And Marines (Explained)

Both the Army and the Marines take great pleasure in having the hardest, most diverse personnel in the American Armed Forces.

The two military service branches have many characteristics, yet they also have differences that set them apart. One important distinction to highlight when contrasting the two branches of the military is the difference in size between them.

The Marine Corps is one of the smaller branches of the US Armed Forces, with the Army being the largest. The Army has a lot more soldiers than the Marines, but because of the Marines’ connection to the Navy, the Army has more varied aviation.

Key Differences:

Army

1. The Army is often made up of land-based combatants who carry out their missions using infantry, tanks, and artillery.
2. Although certain Army special forces are trained in amphibious combat, they do deploy aircraft and helicopters when necessary to aid their ground-based objectives.
3. The Army’s personnel are educated to handle the largest range of tasks across the world.
4. The Air Force and Marine Corps also provide support for the Army, but the Navy is often not a source of assistance.
5. Of the two branches, the Army normally receives the most advanced weaponry first.
6. The Marines’ platoons lack an extra squad for infantry weapons, although the Army’s platoons do.
7. There are several chances to work in a non-combat capacity in the U.S. Army, such as that of a physician, linguist, or chaplain.

Marines

1. It is the duty of the Marine Corps to take and control land, ships, or oil rigs.
2. The fact that the Marines are amphibious fighters—that is, they fight on land via the sea, sometimes necessitating underwater combat—is one of their distinguishing characteristics.
3. Typically, a Marine Expeditionary Unit will have resources available to it in the air, on land, and at sea.
4. The Navy and Air Force will provide support for other forces, whether it takes the shape of ships, planes, or helicopters.
5. The three squads of a Marine rifle platoon are commanded by sergeants.
6. Each squad has three fire teams, each of which is directed by a corporal and consists of a rifleman, an assistant automatic rifleman, and an automatic rifleman.
7. In the Marine Corps, there aren’t as many alternatives for non-combative positions, but there are many other occupations available in other fields like aviation because the Marines have their own air force.

Comparison between Army and Marines

Parameter	Army	Marines
Moto	“This We’ll Defend” is the slogan of the American Army. The War Office first used this catchphrase in 1775, just before the Revolutionary War started.	The commonly used Latin word “Semper Fidelis,” or simply “Semper Fi,” serves as the Marine Corps motto. This means “Always Faithful” in Latin.
Size	There are around 500,00 military members in the Army.	Less than 200,000 Marines are on active duty.
Function	The Army’s duties include ensuring national security and maintaining tranquility.	The Marines’ objective is clearer. The Marines were initially designed to support naval battle, but they have subsequently developed into the United States’ rapid reaction force.
Headquarters	The U.S. Pentagon building in Arlington, Virginia, houses the headquarters of the American Army.	They are stationed in the Headquarters Marine Corps, which is located in Arlington County, Virginia, and has a number of facilities.
Application Restrictions	You must be an authorized permanent resident or a citizen of the United States. Not allowed to enroll are single parents with one or more dependents.	Before enrolling, single parents must submit a waiver and wait a year.
Age Requirements	The U.S. Army requires recruits to be 17 or 18 years old to enroll.	The minimum age to join the Marine Corps is the same as the U.S. Army, however, you must be under 29 years old.
Reports to	The Secretary of the Army, who works under the Secretary of Defence, is the person who the United States Army reports to.	Although explicitly under the Secretary of the Navy’s management, the Marines also answer to the Secretary of Defence.
Operation	Due to the fact that the U.S. Army is predominantly a ground force, it will transport personnel using trucks, tanks, and all-terrain equipment.	The Marines regularly manage Navy-related missions; therefore in addition to Humvees or tanks, they may also deploy ships, submarines, and amphibious vehicles.

Major Differences Between Army And Marines

What exactly is an Army?

An army is a sizable, organized force that is equipped and prepared for battle, particularly on land. The phrase can refer to a sizable force set up for autonomous operations or to the whole military structure of a country or ruler for ground warfare.

Armies have undergone many organizational and character changes throughout history. Due to socioeconomic and political changes in several nations, militaries have undergone changes over time.

The development of new weaponry had an impact on how armies were set up and how the war was fought. Armies have occasionally been formed around foot troops, mounted fighters, or men in vehicles.

They have included experts or novices, mercenaries engaged in pay-for-play or plunder-for-pay battles, or patriots defending their country. The formation of an army must be taken into account in the context of the eras in which it was formed and the conflicts it participated in.

What exactly are Marines?

A military force that is specifically organized, trained, and recruited for duty at sea and in land operations incident to naval campaigns is the Marine Corps. Marines have been employed for many years in history.

Epibatai, or heavily armed sea troops in the Greek fleets, were mentioned by the Greek authors Herodotus and Thucydides in the fifth century BCE and Polybius in the third and second centuries BCE. 

Regular soldiers frequently boarded ships in Europe during the Middle Ages to act as a fighting unit, but it wasn’t until the naval conflicts of the seventeenth century that the British and Dutch nearly simultaneously rediscovered the specific and structured role of marines, establishing the first two modern marine corps.

Although other nations also have marine corps, the United States Marine Corps, which was established in 1775, is now the most well-known of its sort.
