The current President of the United States is Donald J Trump. He is the current Commander-in-Chief of the Armed Forces. All branches except the Coast Guard are part of the Department of Defense, which is controlled by the Secretary of Defense. The Coast Guard is located within the Department of Homeland Security. The Marine Corps located within the Department Of The Navy.

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.^[13]

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.
