It's the first sergeant's job to assist the commanding officer in matters of discipline, administrative work, and the unit's morale and welfare. Regardless of how well this mission is completed in the eyes of the lower-enlisted, earning the rank of first sergeant takes many years of hard work and dedication to the Marine Corps.
Members of the E-8 pay-grade are some of the most interesting and badass Marines you'll ever meet as you climb through the ranks. They come in several varieties:
The former drill instructor
You can easily identify this type of first sergeant. First, listen to how raspy their voice is from years of yelling at recruits during training. This type of first sergeant is outstanding at calling cadences during PT and formation marches — for good reason; they've had plenty of practice.
The one that everyone respects
Once you enter the infantry, you'll begin to judge other Marines and sailors based purely on they the way they look. There's tons of competition within infantry houses; it's our way of sizing up those we must outperform. However, there are a few senior-enlisted Marines whose appearances alone will tell you that they're complete badasses.
You'll look up to these guys.
Some Marines hold audiences captive with riveting speeches while others send people drifting off to sleepyland. Those who can keep your attention speak from their diaphragms and sound off like they have a pair. These vocal commanders are used to addressing whole companies of Marines and have tons of epic stories to tell.
The one who knows every freakin' regulation in the book
An excellent first sergeant knows all the ins-and-outs their job — which is hard. Some troops will (foolishly) try to pull a fast one on the Marine who controls all the administrative work for the entire infantry company. However, these types of first sergeants don't even have to bat an eye when it comes to Marine Corps policy.
They will rattle off nearly every regulation in the book if you try and test them.
The one you can never find
When you need some paperwork signed, this type of first sergeant is never in his office when you go looking for them. So, where the hell do they go? Who the F knows...
