Battlefield Contractor

Crazy Horse has sneaked into a small intersection on the north side with people. Raising his hand to stop the group of brothers, Crazy Horse slowly approached along the shadow of the corner and turned on the thermal imaging equipment.

In fact, strictly speaking, he uses a thermal imager, which is different from night vision equipment. Thermal imaging is not a night vision device. Thermal imaging can be used during the day and night. The effect is the same. The night vision device cannot be used during the day. It can only be used at night to reflect the performance of the night vision device.

A night vision device, if it is in a dark environment such as an underground cave, must be equipped with an infrared light. Since the maximum distance of a general infrared light is 100 meters, the distance for observation and identification is 100 meters.

If it is a high-resolution thermal imager, the observation and recognition distance can reach about 500 meters, of course, the price is much more expensive. Therefore, according to the battlefield environment, in total darkness, unless the resolution of the infrared thermal imaging camera is too low, it will be farther than the night vision camera. In low light conditions, the night vision device will be slightly farther away, but the difference is not big.

But the night vision device can identify who it is and can see every detail, but the thermal imager cannot identify the part without temperature difference.

If it is also used for night operations, for a hidden enemy, as long as the enemy is slightly exposed, the thermal imager can recognize the target, but the night vision device may not be able to recognize it, so night vision and thermal imager There are advantages and disadvantages in night operations.

At night, the temperature of the space is lower than the temperature of the human body. At this time, the human body will form a heat radiation state to the gas in the space. From this point of view, the air temperature within a distance of about 20 cm around the human body must be higher than the air temperature outside of 20 cm. The closer to the surface of the human body, the closer the temperature of the air will be to the human body, and the air will form a virtual human outline outside the body. This is very obvious in the thermal imager.

Crazy Horse observed several times and whispered, "Found the enemy's hidden whistle, one person at the third-floor window right in front. At forty-five degrees to the left, there are two dark whistle. Report the observations from other angles."

"You missed one, on the top of the east building, in your blind spot for observation, enemy sniper." Yelena's voice came from the headset.

"Well, let's divide the work now and see how to do it?" Crazy Horse replied in a low voice. "Give me the most recent one. Who will be responsible for the other two?"

"Let's come!" the two brothers Bassar and Farhad whispered. While installing a muffler on the muzzle, they exchanged opinions in a low voice.

"Leave it to me that sniper." Yelena whispered, "I can see his shoulders."

They have made enough preparations this time, and they are equipped with the latest "vortex muffler" developed by the famous American muffler company OSS. The interface between the muffler and the firearm is complicated in structure and difficult to manufacture. The internal structure is more like a metal tool. It is hard to connect with the barrel at first glance, but it is the best muffler at present.

The United States has been in the forefront of the world in the research of silencing rifles. In recent years, it has designed an integrated silencing rifle weapon and perfected it to equip different arms of various units.

Since the United States is often active in the mediation and fighting of various armed incidents, they have a profound study of war. It is believed that the huge muzzle noise makes most soldiers unable to hear clearly or even completely the command of the captain as long as they stay a little farther, and the command and fire organization ability on the battlefield is greatly affected.

Moreover, it is always difficult to move due to the huge gunfire when beheading in a sneak attack, so this kind of muffler came into being.

Due to the muffler integrated with the barrel, it can be disassembled and assembled without any trouble. Several parts can be assembled successfully in ten seconds. The barrel adopts the most advanced porous sound-absorbing material, and the organic combination of the tube and the chamber at the mutation interface can block the propagation of sound waves and allow the airflow to pass. It is an effective tool for noise control. When the gun is fired, only a slight muffled sound can be heard. It can be used for sneak attacks and beheading operations.

With a few very slight muffled noises, several secret whistles almost collapsed together. Crazy Horse whispered in the wireless communication channel, "The secret whistle has been cleared and the road on the north side is clear. Please ask for permission to walk."

Lin Rui whispered at the door on the east side of the factory, "Keep moving silently, and the target personnel must stay alive."

"Understood." Crazy Horse agreed.

Lin Rui turned around and said to the other brothers, "The arrest team is already in place. It's up to us now. It's time to move forward together."

Sausage whispered to him, "It's okay, the guards at the intersection ahead have been removed, and we can also act."

"Go, you and the Russian follow me to the east assembly workshop." Lin Rui nodded, "Others cover us to make sure that no one gets close while we are acting, or that sentence, acting silently. Exposure means failure. ."

He took Sergey and sausages and walked in through the small door on the flanks of the main door. Since the guards here have also been cleaned up, the only thing that can really pose a threat to them and cause accidents is actually the inspection team of terrorists. These teams kept walking in circles inside the factory, about once every seven or eight minutes.

Lin Rui asked the brothers to stay for them, mainly to guard against this group of people. These inspection teams mainly inspect the guard points on duty. If they find that a guard has been killed, they will immediately sound the alarm. Therefore, other O2 team members must guard this intersection to avoid such a situation.

Lin Rui, Sergey and others touched the door of the assembly workshop, Sergey was in charge of unlocking, and Lin Rui and Sausage were in charge of guarding. Since both Lin Rui and Sergey were injured in the last mission, their actions were somewhat affected, so their current action was actually quite risky.

"How's it going?" Lin Rui whispered, "It's better to unlock the lock quickly, as the patrol team may appear at any time."

"I know, the situation is a bit bad, this lock has some kind of alarm function, I am trying to eliminate it. Otherwise, as long as the workshop door is opened, we will be exposed. Even the Crazy Horse will be alarmed." Sergey In a low voice, some sweat ran down his forehead.

"Alarm device?" Lin Rui frowned.

"Yes, it is some kind of contact alarm device. When the door is locked, the alarm device is also locked. But when the door is opened, the internal circuit will form a path, and the alarm will be triggered, which is equivalent to a switch. Although it is a very simple and crude anti-theft device, the person who set it up should be a good hand. The alarm is very concealed." Sergey whispered, "I have to cut off the alarm to open the door."
