Ranks

The United States Armed Forces are the military of the United States. There are six branches: the United States Army, United States Navy, United States Marine Corps, United States Air Force, United States Space Force and the United States Coast Guard.

The current President of the United States is Donald J Trump. He is the current Commander-in-Chief of the Armed Forces. The Army, Marine Corps, Air Force, Navy and Space Force are connected to the Department of Defense while the Coast Guard is part of the Department of Homeland Security. There are Three Military Departments. Two of them have two services inside them and one has one service inside it:The United States Army is connected to the Department of the Army. The United States Navy and Marine Corps are connected to the Department of the Navy. The United States Air Force and Space Force are connected to the Department of the Air Force.

About 1.4 million people are currently on active duty in the military with another 1,259,000 people on reserve (with 456,000 people in the Army and Air National Guard). There is currently no conscription. Women can serve in most combat positions, and in all non-combat military jobs. Because of war, some of these non-combat jobs actually see combat regularly.

Branches of the Military

There are six main parts, called "branches," of the U.S. military:

Branch What they do
Army The oldest and largest branch. They fight mostly on land.
Navy They use ships and submarines to protect the oceans and seas.
Marine Corps They are experts at landing on beaches and fighting in many different places.
Air Force They use airplanes, jets, and drones to fight in the air.
Space Force The newest branch. They protect U.S. satellites and interests in space.
Coast Guard They protect the coasts of the U.S. and rescue people at sea.

History

In the American Revolutionary War, the U.S. military was formed in 1775. Initially, it was known as the Continental Army and was commanded by George Washington.

The U.S. military has since been engaged in numerous large wars, including:

Personnel (People)

The military has two major categories of persons:

By the year 2026, the number of people on Active Duty (full-time workers) is approximately 1.3 million. Hundreds of thousands of National Guard and Reserves members also train part-time and can be deployed to assist in times of emergency.

Budget and Technology

No other country spends more on military expenditure than the United States. The budget in 2026 can be described as more than 1 trillion. This money is used for:

Ranks

All branches of the United States military have Commissioned Officers and Non Commissioned/Enlisted Personnel. Most Enlisted members with a rank of E-4 and above are called Non-Commissioned Officers (NCOs), the exception is the Air Force where E-5 is considered the first Non-Commissioned Officer (NCO) rank. Their usual duties are to supervise or make sure that common jobs are done properly every day. Most branches of the United States Military include Warrant Officers (Chief Warrant Officers in the Navy.) They are considered experts in their field, they are higher rank than other enlisted troops, but below Commissioned Officer. There are four or five ranks of Warrant Officers in most of the branches: WO-1 through WO-4 or WO-5(CWO-1 to CWO-4 or CWO-5)

Here are some common ranks for the US Army,Air Force and Marines. These branches of the military use different names for the enlisted ranks, but they all use the same for officers. The Navy and the Coast Guard have different ranks; for those see United States Navy. There are no five star general Ranks. The General of the Army, General of the Air Force and Fleet Admiral are only used in wartime situations. The United States Army, Marine Corps, Air Force and Space Force have Commissioned Officer and Non-Commissioned/Enlisted Personnel Ranks with the Navy and Coast Guard also having Officer Ranks. These Titles are seen below.
