Differences between the branches of the U.S. military?

Hi everyone, I've been curious about the different branches of the military and how they each serve unique functions. Can anyone give me a good summary of each, and perhaps highlight the specific role submarines play in the Navy? I'm thinking about options after high school, and the military is one of them. Thanks!

Absolutely! It's an excellent question. Each branch of the United States military has a specific focus, though there's overlap in the types of missions they carry out. Here's an overview:

1. U.S. Army: The Army is the largest and oldest branch of the military. It's responsible for land-based operations and handles major ground combat missions, effectively making it the principal land warfare branch of the armed forces.

2. U.S. Navy: The Navy oversees sea-based operations. It's responsible for carrying out naval operations and securing freedom of the seas. Submarines, as you asked, play a critical role in the Navy's operations. They can conduct various missions, including launching land-attack cruise missiles, gathering intelligence, laying mines, and performing surveillance. In essence, submarines provide a stealth component due to their ability to navigate deep sea undetected, giving strategic advantages in naval operations.

3. U.S. Air Force: The Air Force's domain is air and space. This branch is responsible for aerial military operations, defending U.S. airspace and airbases, and establishing air superiority. The Air Force also provides air support in ground and naval operations.

4. U.S. Marine Corps: The Marine Corps operates as a part of the Department of the Navy and is often considered the maritime infantry of the military. Marines specialize in rapid response and are often the first on the ground in combat situations. Their mission is to seize or defend naval bases and other land operations to support naval campaigns.

5. U.S. Coast Guard: The Coast Guard functions under the Department of Homeland Security. It is responsible for maritime law enforcement, mariner assistance, and search and rescue, among other duties. During a time of war or at the direction of the President, the Coast Guard serves under the Department of Defense.

6. U.S. Space Force: As the newest branch, started in 2019, the Space Force works to protect U.S. and allied interests in space. This includes monitoring ballistic missile launches, tracking space debris, and maintaining satellites.

Remember that each of these branches also has reserve and often guard counterparts that operate part-time in support of the federal mission but may also serve a state governor.

Before making a choice, ensure you take time to extensively research each branch and consider factors like your long-term goals, areas of interest, lifestyle, and the unique character and demands of each service branch. Speak to recruiters as well but ensure you get as many perspectives as possible. You might also find the military's aptitude test (ASVAB) helpful to indicate suitable roles within the military. Speaking to individuals who currently serve or have previously served can also provide you with practical and firsthand insights.
