What Are the Different Branches of the Military?

Today, the U.S. armed forces includes the Army, Navy, Air Force, Space Force, and Marine Corps, all of which operate under the direction of the Department of Defense. The Coast Guard receives commands from the Department of Homeland Security. The National Guard usually receives its directives from state leaders.

Air Force

Before the implementation of the 1947 National Security Act, U.S. military aviation was the joint responsibility of the Army, Navy, and Marine Corps. The act created the National Military Establishment (later renamed the Department of Defense) and established the U.S. Air Force as a distinct branch of the military.

The Air Force currently has over 330,000 active personnel, making it the largest air force in the world.

You may enlist with the Air Force full time or part time with Air National Guard and Air Force Reserve. Advantages include on-the-job training, full college tuition reimbursement, housing allowances, and retirement benefits.


The U.S. Army was established by the Second Congressional Congress in 1775. The Army's mission is to help the U.S. win wars through sustained dominance by seizing and controlling adversaries' land and resources.

Joining the Army can lead to a variety of well-paying, in-demand occupations such as construction engineer, fire control enhanced operator, and air defense system specialist. You can also work as a communications operator who holds important conversations through multichannel transmission systems.

Coast Guard

The U.S. Coast Guard traces its history back to 1790, when it was established as the U.S. Revenue Cutter Service. Today, the Coast Guard works under the Department of Homeland Security during peacetime and operates as part of the Navy upon congressional declaration of war.

The Coast Guard currently employs 42,000 active personnel, with additional career opportunities available in reserve positions.

Marine Corps

Established on Nov. 10, 1775, the U.S. Marine Corps operates under the command of the Department of Defense. The Marine Corps works closely with naval forces to conduct expeditionary missions.

Marines operate by an exceedingly rigorous code of conduct and possess a resilience that can help them adapt to — and overcome — challenges. Outside of military conflict, the Marine Corps contributes to disaster relief missions and other humanitarian efforts.

The Marine Corps also operates the oldest military band. The band performs at over 500 official state functions each year.


In terms of sheer tonnage, the U.S. Navy is the largest navy in the world. The Navy currently boasts 290 deployable combat vessels and more than 3,700 operational aircraft.

Over 347,000 active personnel work for the Navy, and 101,500 additional service members stand by in the Ready Reserve.

As a member of the Navy, you will foster global collaboration by training with foreign navies. General missions center on regional security and may include at-sea rescues and environmental cleanups. Advanced Navy personnel also conduct reconnaissance and intelligence operations.

The U.S National Guard traces its origins back to the first militia regiments formed in the early 1600s. Today, this branch of the armed forces consists of units from all 50 states, the District of Columbia, and the territories of Guam, the Virgin Islands, and Puerto Rico.

Many personnel hold full-time civilian jobs and serve part time as National Guard airmen and soldiers. They receive support from a full-time cadre of active Guard and Reserve members.

By joining the National Guard, you receive pay and benefits for every day you serve, including training, weekend drills, and deployment.

Opportunities run the gamut and usually include administrative positions, STEM careers, and special forces occupations that may enable you to become a Green Beret.

What Are the Different Jobs in the Military?

The U.S. military divides its employees into two categories: enlisted personnel and military officers.

Not all military careers involve combat or its collaterals. You can find a variety of noncombat occupations, including administrative jobs in accounting and human resources.
