When it comes to branch rivalries in the military, you'll find none greater than that between the Marine Corps and the Navy. It may be because we're technically a part of the same branch but, either way, we constantly give each other sh*t for any reason we can find. Even still, Marines and sailors get along quite well — in fact, we probably get along better than any other two branches of the armed forces.
Yes, the Marine Corps is a part of the Department of the Navy, but we're still considered separate branches. We have different goals, but they complement each other's. So, we work closely together. All of those hours spent cooperating means that we've gotten to know each other pretty damn well over the years. Even Marines or sailors who have left the service find the most common ground with their cross-branch counterparts.
Here are a few reasons why Marines and sailors so often end up as the best of friends:
Our relationship is symbiotic
Even though Marines tend to do all the heavy lifting, the Navy is usually right there with us to share the burden of being the greatest war fighting faction ever to exist. In fact, because Marines are amphibious, we need the Navy to cart us around — like our own personal taxi service.
Marines and sailors share manpower
As part of that symbiotic relationship, the manpower between the branches is often shared. The Marine Corps uses Navy Corpsman for medical needs and aviation units in either branch are often filled out with a mix of mechanics from both sides.
We can constantly joke about each other
One thing you'll find is that Marines have plenty of jokes for Sailors and vice versa. Furthermore, you'll find that we can both take the jokes quite well. Hell, we even share a notoriety for being a bunch of drunken bastards.
Marines and sailors have the best military uniforms
Marines have the best uniforms ever conceived by any military branch — but the Navy comes in at a (distant,) solid second place. Both of our branches have the most recognizable and aesthetically pleasing uniforms out there. Sure, we may not wear berets, but we have sexy dress blues. The best part of it all? A Navy corpsman embedded in a Marine unit, referred to as "green side," can choose to wear the Marine dress blues.
They're our closest sibling
Marines don't have as much of a working relationship with other branches as they do with the Navy. Ever since the planet was blessed with United States Marines, the Navy has been right there alongside us, fighting and winning every battle we possibly can.
