Unification of Military Branches - Feasible or Not?

I've been giving some thought to military service as a possible path post-high school, but I'm having trouble understanding why the military branches are separate entities. Can't they all be unified? Wouldn't it make more sense if everyone trained together for better cohesiveness?

This is a complex question! The organization of the U.S. military into separate branches has been a highly debated topic for many years. It largely comes down to the diversity of the tasks each branch is responsible for, which can require specialized training and resources. The military branches each have their own distinct cultures, operating procedures, tactical doctrines, and even jargon, all shaped by the unique demands of their roles.

Just to illustrate, the Army primarily conducts land-based operations. They need to understand geography and logistics in a way that’s very different than, say, the Navy, which focuses on sea warfare. The Navy needs to understand nautical navigation, how to operate in deep-sea environments, and how to maintain and operate gigantic vessels. Meanwhile, the Air Force focuses on aerial warfare and maintains a fleet of aircraft and space assets.

For instance, Space Force, the newest branch of the military, is specialized in protecting U.S. and allied interests in space, by monitoring ballistic missile launches, tracking space debris, and maintaining satellites that allow the other branches of the military to communicate. They require a unique expertise and skill set that's distinct from the other branches.

Although unifying all branches on the surface seems like it would promote cohesion and perhaps even be more cost-effective, the reality is that warfare and defense are highly specialized fields. It's important for each branch to be able to refine and advance their own unique tactics, training, and procedures. There are indeed unified commands where branches work closely together, especially during joint operations, but the backbone of the military service comes from individuals who are highly trained and specialized in their respective fields.

However, you have a point about the importance of increasing inter-branch cooperation and coordination. Military branches often train together in joint exercises and share technologies and strategies where they overlap. This kind of cooperation does promote a certain level of unification without losing the unique benefits each branch brings to the table.
