Here are the major lessons I learned from carrying the M27

Following the rulebook isn't always a necessity. Well, that's how the Marine Corps infantry feels about doctrine, anyway. Sure, there are hundreds of people who put their great minds together to come up with standard procedures for everything relating to warfare, but even still, us grunts take those "procedures" as suggestions. Why? Simple. We recognize that what may work for one unit doesn't work for everyone.

This is the case with the fire team billet of "automatic rifleman." The position is supposed to be held by the team leader's second in command, usually a trusted advisor who can help run the team. But, over the years, Marines thought of a better person to hold the billet: boots. New guys. The FNGs. While some higher-ups might see this as hazing, the down-and-dirty, crayon-eating grunts disagree.

We argue that being an automatic rifleman teaches you these valuable lessons:

Accuracy is key. Pay attention and you might even score higher on the next qualification range.

Accuracy

Some battalions have what's called a "Squad-Level Advanced Marksmanship Course," which is a fancy, Marine Corps way of saying, "automatic rifleman course." That's essentially what it is. But the focus is, as the name suggests, on marksmanship. Why? Because to be a good automatic rifleman, you must first be a good rifleman.

Learning how to engage accurately with an automatic weapon also teaches you how to be a substantially more effective rifleman. After all, you're firing a high volume of bullets and, the more accurate you are, the more devastating to the enemy you are.

You'll want to let the rounds fly, but each one is important. Always be mindful of that.

Ammo conservation

It's no secret that you get a lot of ammo as an automatic rifleman — around 18-22 magazines, to be exact, most of which you'll be responsible for lugging around. But while learning about accuracy, you might also learn about conserving ammo.

The idea is this: You need to have enough ammo at the end of the fight to move on to the next fight. Especially if you're the automatic rifleman, your fire team needs you.

This lesson of control can even help you as a leader, telling your automatic rifleman what you want them to do.

Control

Quickly, you'll learn that an automatic rifleman shouldn't just unleash a barrage of bullets. You'll learn when it's appropriate to fire on full auto and when it's appropriate to fire in 5-6 round bursts into large groups of enemies. This is important because, as you move up in rank and experience, you'll be able to teach the next automatic rifleman about control.

This same control will help you with ammo conservation. More importantly, all these lessons will follow you into other fire team positions. In fact, if you become a squad leader, knowing how to use your automatic riflemen will be easier if you've been one.
