And winter boots; 4 underwear; ⑤ Cold gloves. Daily necessities mainly include: ① rations (standard is two days); 2 raincoats; 3 toiletries; ④ medical care

Manual.

Here will focus on: M9 multifunctional bayonet commonly used by US special forces; Gas mask; Night vision glasses; Global positioning system receiver;

Portable radios and other personal devices.

M9 multifunctional bayonet

This bayonet is equipped with scabbard, which can be used with "Alte" MOD733 assault rifle and other M 16 rifles. Its characteristics are as follows

Steel is good, sharp and tough. Even if it falls vertically on the concrete floor from the height of 1.5 meters, the blade will not roll; After the blade is slightly twisted by external force, it can still

Return to the original state. This knife weighs 0.82kg, with a total length of 3 1cm and a serrated back. The scabbard and the back of the knife are combined into one, which can be used as steel scissors.

M40 gas mask

The M40 gas mask is part of the American special warfare team who just put on the new gas mask. Compared with the original M 17 gas mask, the differences are as follows: ① gas protection.

Compared with M 17 gas mask, its performance is improved by 3 ~ 5 times, because the material of M40 gas mask uses silicone rubber instead of isobutylene rubber, and the sealing performance is greatly improved. ② Increase

A voice amplifier for internal communication and an eye mask to protect eyes from laser damage are added. But the disadvantage of this new gas mask is that

So, although its laser goggles can protect your eyes from the laser from the other laser sight, you can't use the laser sight yourself.

Or laser ranging.

Night vision glasses

American special forces are equipped with different kinds of night vision goggles, among which the new passive infrared thermal imaging night vision goggles are characterized by small size and light weight (1).

Generally 0.4 ~ 1 kg), it has the function of identifying camouflage and penetrating clouds, smoke and fog, and can observe people 400 ~ 800 meters away, 1500 ~ 4000 meters away.

Infantry formations, tanks, chariots and other targets; Combined with helmet, shooting, ranging and command equipment, it can form a whole of protection, observation, aiming and shooting.

Body. Like AN/PVS? 5.7 Can night vision glasses (only weighing 170g) be used with AN /PAQ? 4 infrared indicator and night vision device are used together. In a pistol,

After being mounted on a light weapon such as a rifle, the infrared beam emitted by it is corrected to be parallel to the axis of the gun bore, so that the shooter can see the aim on the target clearly through night vision glasses.

The infrared light spot emitted by the device can pull the trigger and aim at shooting when the light spot shines on the target.

Global positioning system receiver

199 1 At the height of the Gulf War, we often saw such a puzzling picture on the TV screen: a man with a weapon.

Pretending to be an American soldier, he lowered his head and fiddled with something that looked like a game machine. In fact, this is the first time that the United States has used global policy in the war.

Micro receiver of bit system (GPS).

The so-called "global positioning system" is a global unified military satellite navigation system established by the US Department of Defense for the US military since the early 1970s.

It consists of three parts: space, control and ground users. The space part is evenly distributed at six angles of 55, about 2000 kilometers from the ground, and the period (that is, the ring

The time to circle the earth is 12 hour. Each satellite is equipped with a high-precision atomic clock, and it takes 30,000 years for the error to reach 1 sec. Available ones are 1.575.42 MHz and.

1227.6 MHz frequency transmission navigation signal continuously transmits L-band carrier transmitter, which ensures that ground combat troops can receive four GPS anywhere.

Radio waves emitted by satellites. Can each satellite modulate three kinds of pseudo-random noise: P code (fine code), G/A code (coarse code or S code) and Y code (encrypted P code)? P

Code and Y code are only used by the military departments or authorized civilian departments of the United States and its allies. The once positioning accuracy of P code is 10 meter, and it can reach sub-level after multiple positioning.

Within meters or even centimeters; . C code can be used in civil use, with a once positioning accuracy of 25m and a multiple positioning accuracy of 8m. The control parts are located in the Atlantic Ocean.

Ascension, Diego Garcia in the Indian Ocean, Guam, Hawaii and Kwajalein in the Pacific Ocean. The main station is located in the United States.

Colorado springs. The ground user part is used to receive satellite information, which can be calculated and processed to determine the GPS connection of its position.

Put the machine away. The existing receivers are divided into six categories, namely, single-soldier single-pass backpack type, ground vehicle-mounted type, helicopter dual-channel type, fighter, bomber and nuclear submarine.

Use the 5-channel type and so on. The smallest receiver, which looks like a game machine, is as big as a cigarette case and weighs 1.5 kg. It is very flexible and convenient to use.

The global positioning system (GPS) is characterized by continuous positioning around the world for 24 hours, and continuously provides three-dimensional space for various combat troops or other users.

Position, three-dimensional velocity and time signals.

The model of the United States Army is M 134 rapid-fire machine gun. Gatling) 7.62 Ammunition minigun is widely used. The model of the US Air Force is GAU-2 B/A, and the model of the US Navy is GAU-17/A. At present, this rapid-fire machine gun has a maximum firing rate of 6,000 rounds per minute, which is called the fastest machine gun in the world. The machine gun was developed by the former General Electric Company (now Lockheed Martin Ordnance Systems Company) on the airborne M6 1Al Vulcan 6-tube rapid-fire gun in the early 1960s, and its series caliber ranges from 5.56 mm (0.223 inch) to 25 mm (1.0 inch). At first, the US Air Force redesigned and developed six GAU-2 aviation machine guns with a diameter of 7.62 mm, which were driven by electricity and operated by a crew member. It is used in light aircraft and helicopters of the US Air Force, and its extremely high firing rate is amazing. It was widely used in the Vietnam War.
