After spending two to three months in boot camp, young troops who are looking to serve in the infantry must move onto additional grunt training at other various grounds.
Once they graduate from that, some head off to their first units, where they'll encounter some interesting personalities.
Some of these exciting personalities exist in the diverse troops who carry the "big guns" — aka, the machine-gunners.
1. The "Marksman"
An infantryman works and trains hard to one day deploy their weapon system and score an accurate kill shot. For machine-gunners, scoring a precise kill from a distance is highly unlikely.
This isn't because the shooter is incapable; that weapon system wasn't designed to nail an enemy combatant square between the eyes but, rather, to take their head clean off.
However, some gunners still strive to make that perfect shot with their heavy-ass weapon.

2. The "Napoleon"
This one refers to the French military leader, Napoleon Bonaparte, because of his height. This gunner gets looked at differently because of the contrast between their smaller body and the massive size of the M240 they're holding.
However, they always manage to carry it and fire the weapon like a seasoned pro.
3. The "Screamer"
Machine-gunners are trained to whisper the words "die motherf*cker, die" while firing their weapon. In the time it takes to finish saying the words to themselves, they've shot roughly between four to six rounds. The "screamer" chooses to shout that sh*t out loud.
This repeated mantra is designed to prevent the gunner from overheating their barrel and causes them regularly adjust their fire for more accuracy.

4. The "Barrel-burner"
As previously stated, machine-gunners are trained to only discharge four to six rounds at a time to avoid overheating their barrels. The "barrel-burner" tends to forget the shooting cycle and fires more than intended — which can cause the barrel to warp.

5. The "Freeloader"
This gunner tends to ask other members of his squad to carry his extra ammo so that they can haul more Rip-Its. What's hilarious about this type of gunner is the nice way they go about asking you.
It makes you feel good about yourself for helping out a brother.
6. The "Animal Mother"
If you've ever served in the infantry, you probably had one or two "Animal Mothers" in your company. Just like in the movie, Full Metal Jacket, he's the trigger-happy badass who is more than thrilled to shoot into an enemy compound and then ask questions later.
