How many branches are there in the US military?

I'm doing some research on the US military and it's getting a bit confusing with all the distinct branches. Could anyone please tell me exactly how many branches are there and maybe provide a brief description of each? I'd really appreciate your help! Thanks!

There are six branches in the U.S. military, each with their own unique missions and structures. Here's a brief overview of each:

1. Army: The Army is the oldest established military branch in the U.S. Its primary duty is to conduct land-based operations, but its responsibilities extend to air and sea.

2. Navy: The Navy specializes in combat operations in the ocean or on the high seas. They control naval ships and submarines to engage in warfare, and also have their own air force called the Naval Air Force.

3. Air Force: The Air Force controls most of the flying missions for the military. It is mainly responsible for aerial warfare, and it uses airplanes, helicopters, and drones to carry out operations.

4. Marine Corps: The Marine Corps serves as an expeditionary force, meaning that they are often the first boots on the ground in times of conflict. They are known for their rigorous training programs and their ability to conduct operations by air, land, and sea.

5. Coast Guard: The Coast Guard has a unique role. During peace times, it's a part of the Department of Homeland Security, and it enforces laws, conducts rescue operations, and guards the coasts. During times of war, it can be transferred to the Department of the Navy.

6. Space Force: The Space Force is the newest branch, established in 2019. It protects U.S. and allied interests in space, and its duties include monitoring ballistic missile launches, tracking space debris, and maintaining satellites that allow the other branches of the military to communicate.

Each branch plays a critical role in maintaining the safety and security of our country.
