What's the military branch counterpart of diplomacy?

I'm quite interested in international relations and the diplomatic side of things, and I was wondering if there's a branch of the U.S. military that has similar tasks or priorities? I've been looking at all my options post high-school and want to explore this possibility.

There's not a specific branch of the U.S. military dedicated solely to diplomacy because, by nature, the military mainly engages in defense operations. However, various sub-departments within each branch engage in diplomatic tasks and missions that couple military power with diplomatic negotiations. The closest entities could be:

1. The Defense Attaché Service (DAS): This organization is a part of the Defense Intelligence Agency and operate in more than a hundred countries. These are military personnel appointed as Defense Attachés who represent the Secretary of Defense, the Secretary of the military department (Army, Navy, Air Force), and the senior defense official or U.S. ambassador in the country where they serve. Generally, their roles often involve defense and military diplomacy, providing military advice to the U.S. ambassador, and coordinating and reporting on military matters in the host country.

2. Civil Affairs units: Primarily the role of the Army Reserve and a small component of the Army Special Operations community, Civil Affairs soldiers help military commanders by working with civil authorities and civilian populations in the commander's area of operations to lessen the impact of military operations on them during peace, contingency operations and declared war.

3. The Naval Diplomat: Though not exclusive to international diplomacy, the Navy sometimes works with foreign navies to maintain healthy relations, participate in allied military exercises, and help maintain global stability.

4. The United States Air Force's Air Adviser role: In this role, service members are often positioned overseas, building relationships with international partners, advising on U.S. air capabilities and training.

Overall, all branches of the military engage in some form of diplomatic work as part of peacekeeping missions or international partnerships, but these roles provide more directly related experiences. Remember, it's essential to carefully research any military commitment, considering both the advantages and obligations, as serving in the military is a significant commitment and far different from civilian life.
