The M2 Browning Machine Gun (M2MachineGun) is commonly known as the 0.50 Heavy Machine Gun (BrowningMachineGun, Cal.). 50, M2HB, Flexible.), is a large-caliber heavy machine gun designed by John Moses Browning, firing 12.7×99 mm (.50BMG) large-caliber ammunition, commonly used in infantry erection of fire positions and military vehicles such as tanks, armored personnel carriers, etc., the main purpose is to attack lightly armored targets, assemble living targets and low-altitude air defense, from 1921 to the 21st century.

The gun uses the principle of short recoil of the barrel and the locking structure of the clamp iron landing type. When firing, as the warhead moves forward along the barrel, the barrel and bolt recoiled simultaneously under the pressure of gunpowder gases in the chamber. After the warhead flies out of the muzzle, the locking iron leaves the locking bearing surface on the wedge latch, and the pins on both sides of it are pressed down by the unlocking slope on the shaping plate, so the entire locking card iron is separated from the locking groove under the bolt, and the bolt is unlocked. Subsequently, the barrel sleeve slammed into the hook-shaped accelerator inside, and the upper end of the accelerator hit the tail of the bolt, accelerating the bolt recoil. The gun is equipped with a hydraulic buffer mechanism, when the barrel and the knot sleeve recoil, the piston of the hydraulic buffer is pushed backwards, compressing the oil in the buffer tube, so that it escapes forward from the gap between the inner walls of the oil pipe around the piston, and has a cushioning effect on the recoil. When the bolt is re-entered, the bulge at the tail of the bolt hits the upper end of the accelerator to make it rotate forward, and the accelerator releases the hydraulic buffer spring to push the barrel and the knuckle sleeve to re-advance. The locking card iron is forcibly lifted up under the action of the locking slope on the wedge latch, and enters the locking groove under the bolt, and the bolt is locked.

The gun adopts a single-way ammunition delivery and two-way ammunition feeding mechanism, and the guide post at the end of the lever is stuck into the curve groove at the top of the bolt, and when the bolt is in reciprocating motion, the bullet feeding action is realized.

The gun used a simple sheet front sight and a vertical frame ruler, both of which were mounted on the receiver.

The gun fires 12.7×99mm caliber bullets, including ordinary bullets, armor-piercing incendiary bullets, armor-piercing bullets, tracer bullets, armor-piercing tracer bullets, armor-piercing incendiary tracer bullets, shell-piercing armor-piercing bullets, hard-core armor-piercing bullets, training bullets, etc.

The M2 Browning large-caliber heavy machine gun has a maximum range of 2,500 m (1.9 mi) when firing M2 ordinary rounds, and an effective range of 1,800 m (1.2 mi) on an M3 tripod. The M2 Browning large-caliber heavy machine gun weighs 38 kg (84 lb) net, its M3 tripod weighs 20 kg (44 lb) full, and the V-trigger is mounted at the tail of the receiver with two grips, allowing the shooter to adjust fully automatic or semi-automatic firing by locking or opening the bolt. The M2 is versatile, and in order to cope with different equipment, it can be changed to the right side of the receiver for a short period of time without the need for special tools.

In the face of such a sharp heavy weapon, the damage suffered by the warriors was enormous, but even so, the battle began recklessly.

When fighting against the M2, the weapons in the hands of the volunteers became like toys in the hands of children, with no suppressive power at all, and the enemy's bullets were unbearable even if they only hit the arm.

The M2 in the dark night is the real harvesting weapon on the battlefield, a soldier who controls it on a light armored vehicle, his hands are tightly gripped, his mouth is roaring, finger-thick bullet casings jump out of the bullet window on the gun, just the number of bullet casings has been piled up next to the armored car A small mountain bag, with the residual temperature of the bullet casings melted the snow on the ground, flowing to the ice water everywhere, just like the fallen volunteer soldiers, blood flowing from their chests.

This kind of killing weapon, which is also extremely terrifying in range, has once again faced a severe test for the 38th Army, and the disadvantages of short hands have been highlighted, and the farthest weapons in their hands will not exceed the number of kilometers.

Hit by the bullets with the wind and lying on the ground, Ma Youde gnawed a mouthful of snow, and the coldness in his mouth made his heart cold, and when the snow was swallowed by him, he was on the snow, withstanding the continuous rain of bullets, and quickly climbed forward for thirty or forty meters.

"Lower your head, keep your head down, don't let me see your ass high above your head, use the crawler, don't get up!" Wei San yelled at the soldiers of the third company.

At this time, the troops of the two sides were about 800 meters apart, and they were about to enter each other's firing range, and the heavy machine guns of the US troops became easier to hit, and after knocking down five or six people in a row, Wei San shouted loudly in a hurry, the soldiers' spirit of not being afraid of death is good, but they must also avoid unnecessary sacrifices.

It's still nearly a kilometer away, isn't it too unjust to fall?

As a unit in the front line, the 38th Army had to suffer a lot of damage, and if the attrition of the troops was not controlled, it was likely that it would not even have a chance to make contact, and it would be annihilated by the enemy from a distance.

After everyone crawled and moved to a distance of 400 meters, the American artillery began to roar, and for a while the density of the shells was almost catching up with the raindrops, and an overwhelming feeling came head-on.

"Coax~" The sea of fire exploded in the no-man's land between the two armies, and if the 38th Army continued to advance, the next wave would not bring up just dirt.

Originally, the snow in front of it was still white, but under this round of artillery fire, it turned into a black area, and the deep crater still had a scorching temperature, but at this time, the soldiers of the 38th Army couldn't care so much.

The free foxhole provided to them by the U.S. military is not necessary, this is originally to eliminate the artillery fire of the living forces, but it indirectly provides a hiding place for the volunteer soldiers, and the disadvantage is that the temperature in the crater is a bit unbearable.

The charge of nearly 10,000 people is extremely spectacular, especially the charge that is concentrated at one point, the last round of artillery fire has provided a sufficient buffer zone for these people, and the troops have been unified again, and their bodies have been warmed up by the high temperature in the crater, isn't it an excellent opportunity at this time, Li Yunlong, who also jumped into the crater, happened to squat with Wei San and the others.

Li Yunlong, who had a snowy head and an angry face, stretched out his head and looked out of the pit.

"T damn, this Yankee guy is really powerful, he can hit it from such a distance, what kind of gun is this? When Lao Tzu takes here, I have to wring a few handfuls of it! ”

Wei San took out some of the ammunition that Gao Baoguo was carrying, and said to Li Yunlong: "This is a Browning heavy machine gun, the range can be up to two kilometers, can the range of large-caliber bullets not be far?" Division, I said that you should not rush too far ahead, in case there is a bit of a situation, we can't protect you! ”

Li Yunlong's eyes glared: "You recruit who just touched the gun still protects me, Lao Tzu has been fighting for so many years, who has protected me?" The Yankees want my life, so I have to exchange them for their American emperor! ”

Wei San clenched his gun tightly and said with a smile: "Their emperor is called the president." ”

"Don't talk about this, you guys, the next round of shells is coming, and when you dodge, follow me and rush quickly! Aim for this breakthrough of 100 meters. Li Yunlong began to command.
