 American special forces buy new machine guns: effective range of 2km, which can be carried by individual soldiers


The total weight of the mag338 machine gun is only 20 pounds, less than 10 kg, which is at least two kilograms lighter than the main medium caliber machine gun m240b currently equipped by the U.S. Army, but their power is far from the same.

The effective range of mag338 is up to 2000 meters, twice as far as m240b, and the kinetic energy of bullet is almost twice as large. The storage speed of bullet 338 at a long distance point is far higher than that of bullet 7.62 mm, so the actual power is more than double.

The bullet used in mag338 is not the Lapa magnum bullet used in the point 338 sniper rifle, but the Norma magnum bullet. The biggest difference between the two bullets is the shell length.

Point 338 Lapa is 8.6 u00d7 70mm, point 338 noma is 8.6 u00d7 64mm, Lapas warhead weighs 16.2g, its initial velocity is 897m / s, its warhead weighs 19.44g, its initial velocity is 808m / s, and their kinetic energy is close, the former is 6516j, the latter is 6300j.

By contrast, the kinetic energy of the 7.62mm NATO projectile currently used by the US military is only 3275 joules, which is not a little bit worse.

Because the initial velocity of point 338 Lapa bullet is much higher, the ballistic performance is better, but the recoil force is also greater, so it is usually used as a special bullet for sniper rifle. The initial velocity of Norma bullet is lower, and the recoil force is softer, so it is used as machine gun bullet. They have the same caliber, but they cannot be used in common.

However, the mag338 can also fire 7.62mm bullets as long as the components such as the gun barrel and barrel are replaced.

To be honest, the function of this caliber conversion has always been a weak point for the author. In wartime, if a soldier takes his gun and asks an Ordnance Officer to change the caliber by changing parts, the Ordnance Officer will most likely directly take out a complete gun for him. This is normal operation.

For a long time, the US military has been equipped with three caliber machine guns, including 5.56mm small caliber machine guns, 7.62mm medium caliber machine guns and 12.7mm heavy machine guns.

The three kinds of machine guns correspond to different combat environments, and basically achieve the coverage of short, medium and long distance.

So why does the US military add another dimension?

In short, there are two main reasons.

Mag338 machine gun uses ammunition chain to supply ammunition, which can be carried and operated by individuals like M240

But it is not feasible to reduce the weight of heavy machine gun, because the weight of heavy machine gun is also its own advantage, it can ensure the stability of shooting, the huge recoil force of 12.7mm bullet must be offset by the corresponding body weight.

To reduce weight by force, the U.S. military only gets a 12.7mm machine gun that can barely be fired. As for the accuracy of service life, dont think about it. Whats more, its impossible to reduce the 12.7mm machine gun to 10kg.

The point 338 bullet perfectly conforms to the above characteristics. It can hit far and accurately, and the weight of the machine gun can also be controlled.

Second, with the rapid development of individual protection ability, the 7.62mm full force bullet of the former power bar has become less rigid. In front of the fourth level bullet proof vest, even the m80a1 bullet, whose penetration can be called the anti sky bullet, can not be said to penetrate absolutely.

At the end of the day, the power of a bullet depends on its kinetic energy, which is not enough. No matter how excellent the warhead structure is, its useless.

The kinetic energy of more than 6000 joules of point 338 bullet, even ordinary steel core bullet, can wear bullet proof clothing without pressure. Even if it cant, the huge kinetic energy will be enough for the enemy soldiers to drink a pot.

The progress of bullet proof vests forces the us to upgrade its caliber, which is also the trend of the development of light weapons in the future. After all, the US military is ready to completely eliminate the 5.56mm caliber bullets.

It has to be said that sig company can control the mag338 to a full weight of 20 pounds, which is quite good indeed.

The reverse example is the 88 type general machine gun, whose caliber is only 5.8mm. The whole gun weighs 11.8kg. Its small, powerful and heavy. No wonder it will be eliminated.

Will the purchase of 338 mm machine guns by U.S. special forces lead to a full-scale reshuffle of U.S. troops?

(function() {(window. Slotbydup = window. Slotbydup| []). Push ({ID: u5811557, container: ssp_, async: true});)) (); in the short term, the U.S. military has no urgent pressure to replace all medium caliber machine guns. After all, the base number of M240 equipment is there, and the inventory of 7.62mm Nato bombs can be regarded as a huge amount. At present, the actual belligerents of the US Army are not standard equipment. But in the long run, the replacement of 7.62mm caliber with point 338 caliber machine gun is basically OK, which is the general trend. In addition, the United States has a congenital advantage that a huge private market can digest the massive inventory of bullets eliminated by the military. This is something that other countries cant and cant envy. Source: Wang Yitan Bing, editor in charge: Yao Wenguang, nn1682

In the short term, the U.S. military hasnt pressed to replace all medium caliber machine guns. After all, the base number of M240 equipment is there, and the inventory of 7.62mm Nato bombs is also huge.
