Histories and Hierarchies: which is the second oldest military branch?

I was playing trivia with my friends (yeah, we're those kind of nerds) and I got stumped on a question about the order in which the US military branches were established. Anyone know which is the second oldest and some history behind it? This might sound weird, but I sorta believe knowing the history of a place helps you fit in more. Could be useful if I end up enlisting.

The United States Navy holds the claim to being the second oldest military branch, established on October 13, 1775. Initially, the Continental Congress didn't see the need for a navy, mainly focusing on land warfare where their primary resources went. However, as the American Revolutionary War progressed, the necessity for a naval force became apparent.

The primary goal was to disrupt the British supply chain and force them to divert resources to protect their maritime interests. Early in its formation, the Navy managed several successful naval operations, which played a critical role in America's victory in the war. Still, it was disbanded shortly after the Revolutionary War in 1785 due to financial constraints.

However, it didn't take long for Congress to realize the necessity of naval forces for the young nation's defense. With increasing conflicts and piracy threats to American merchant vessels in the Mediterranean Sea, Congress officially reestablished the U.S. Navy on March 27, 1794, marking the formal creation of the Navy as we know it today.

Known for its intellectual rigor, technical expertise, and skill at sea, the Navy's principle has long been to keep the peace and deter potential adversaries from reaching American shores. It focuses on maintaining the freedom of the seas, supporting U.S. interests at home and abroad, and projecting power worldwide to safeguard the country's security objectives. Navy personnel are traditionally called "sailors" and their command structure, consisting of ranks and rates, revolves around experience and skill levels.

It's definitely not weird to want to understand the history of a potential career choice; in fact, it's quite admirable! Understanding the history, traditions, and values of an institution can give one a deeper sense of connection and pride, whether it's a university, a company, or a military branch.
