People want to know how tanks with thick armor and closed doors and windows aim at the target and communicate with the outside world, especially how passengers talk when there is a lot of noise inside the tank.
There is no mystery here. The key is that tanks have special and alert "eyes" and "ears".
Look at the eyes of the tank first. Modern tanks use more advanced periscope. It already has several skills, such as farsightedness, night vision and ranging.
If you pay attention, you will see many small windows on the tank body and turret, and periscope sights are installed in the holes. These countless periscopes are the eyes of tanks. They can be used for observation, aiming and distance measurement.
Some of these "eyes" can see distant targets clearly during the day, and even observe and aim through clouds, rain, snow and smoke; Some are like cat's eyes at night, which can still capture the target in the dark night.
In the Gulf War of 199 1, the "cat's eye" night vision goggles equipped by American tanks can clearly see the targets within the range of1/km in the dark.
There is also a low-light-level night vision device, which can amplify the weak light at night such as starlight and moonlight by nearly 60,000 times, so that vehicles four kilometers away and people one kilometer away can be found.
On the command tower of the tank commander, there are four to ten observation periscopes for the commander to observe and aim at, one command periscope, and some are also equipped with optical ranging observation sights, so that the commander can look around the battlefield 360 degrees, search for targets, and command the battle with the windows closed.
The "eyes" for tanks to observe the scenery at night are infrared night vision devices and low-light-level night vision devices.
