Part 16 (2/2)

Let's talk about each weapon individually.

Mk-12

Officially, the United States Navy Mk-12 Special Purpose Rifle, this gun has a sixteen-inch barrel, but is otherwise the same platform as an M-4. It fires a 5.56 45 mm round from a thirty-round magazine. (It can also be fitted with a twenty-round box.)

Derived from what became known as the .223 cartridge and therefore smaller and lighter than most earlier military rounds, the 5.56 is not a preferred bullet to shoot someone with. It can take a few shots to put someone down, especially the drugged-up crazies we were dealing with in Iraq, unless you hit him in the head. And contrary to what you're probably thinking, not all sniper shots, certainly not mine, take the bad guys in the head. Usually I went for center ma.s.s-a nice fat target somewhere in the middle of the body, giving me plenty of room to work with.

The gun was super-easy to handle, and was virtually interchangeable with the M-4, which, though not a sniper weapon, is still a valuable combat tool. As a matter of fact, when I got back to my platoon, I took the lower receiver off my M-4 and put it on the upper receiver of my Mk-12. That gave me a collapsible stock and allowed me to go full-auto. (I see now that some Mk-12s are being equipped with the collapsible stock.)

On patrol, I like to use a shorter stock. It's quicker to get up to my shoulder and get a bead on somebody. It's also better for working inside and in tight quarters.

Another note on my personal configuration: I never used full auto on the rifle. The only time you really want full auto is to keep someone's head down-spewing bullets doesn't make for an accurate course of fire. But since there might be a circ.u.mstance where it would come in handy, I always wanted to have that option in case I needed it.

Mk-11

Officially called the Mk-11 Mod X Special Purpose Rifle and also known as the SR25, this is an extremely versatile weapon. I particularly like the idea of the Mk-11 because I could patrol with it (in place of an M-4) and still use it as a sniper rifle. It didn't have a collapsible stock, but that was its only drawback. I would tie the suppressor onto my kit, leaving it off during the start of a patrol. If I needed to take a sniper shot, I would put it on. But if I was on the street or moving on foot, I could shoot back right away. It was semiautomatic, so I could get a lot of bullets on a target, and it fired 7.62 .51 mm bullets from a twenty-round box. Those had more stopping power than the smaller 5.56 NATO rounds. I could shoot a guy once and put him down.

Our rounds were match-grade ammo bought from Black Hills, which makes probably the best sniper ammo around.

The Mk-11 had a bad reputation in the field because it would often jam. We wouldn't have jams that much in training, but overseas was a different story. We eventually figured out that something to do with the dust cover on the rifle was causing a double feed; we solved a lot of the problem by leaving the dustcover down. There were other issues with the weapon, however, and personally it was never one of my favorites.

.300 Win Mag

The .300 is in another cla.s.s entirely.

As I'm sure many readers know, .300 Win Mag (p.r.o.nounced ”three hundred win mag”) refers to the bullet the rifle fires, the .300 Winchester Magnum round (7.62 67 mm). It's an excellent all-around cartridge, whose performance allows for superb accuracy as well as stopping power.

Other services fire the round from different (or slightly different) guns; arguably, the most famous is the Army's M-24 Sniper Weapon System, which is based on the Remington 700 rifle. (Yes, that is the same rifle civilians can purchase for hunting.) In our case, we started out with MacMillan stocks, customized the barrels, and used 700 action. These were nice rifles.

In my third platoon-the one that went to Ramadi-we got all new .300s. These used Accuracy International stocks, with a brand-new barrel and action. The AI version had a shorter barrel and a folding stock. They were bad-a.s.s.

The .300 is a little heavier gun by design. It shoots like a laser. Anything from a thousand yards and out, you're just plain nailing it. And on closer targets, you don't have to worry about too much correction for your come-ups. You can dial in your five-hundred-yard dope and still hit a target from one hundred to seven hundred yards without worrying too much about making minute adjustments.

I used a .300 Win Mag for most of my kills.

.50 Caliber

The fifty is huge, extremely heavy, and I just don't like it. I never used one in Iraq.

There's a certain amount of hype and even romance for these weapons, which shoot a 12.7 99 mm round. There are a few different specific rifles and variations in service with the U.S. military and other armies around the world. You've probably heard of the Barrett M-82 or the M-107, developed by Barrett Firearms Manufacturing. They have enormous ranges and in the right application are certainly good weapons. I just didn't like them all that much. (The one .50 I do like is the Accuracy International model, which has a more compact, collapsible stock and a little more accuracy; it wasn't available to us at the time.)

Everyone says that the .50 is a perfect anti-vehicle gun. But the truth is that if you shoot the .50 through a vehicle's engine block, you're not actually going to stop the vehicle. Not right away. The fluids will leak out and eventually it will stop moving. But it's not instant by any means. A .338 and even a .300 will do the same thing. No, the best way to stop a vehicle is to shoot the driver. And that you can do with a number of weapons.
