5 popular myths about weapons of cinema

The film battle scenes are always the most spectacular, whether ancient armies battle with swords and bows, naval battles and battle alien to their space weapons.

However, this war has nothing to do with the idea, which was formed in our heads thanks to Hollywood ...

1. This Sniper longer relies on the accurate calculation than a keen eye

Even in the most superrealistichnogo movie scene with the snipers are very similar to a computer game. The shooter finds a secluded place, following the enemy by using special optics and a good aim, pulls the trigger.

In fact, in modern air combat planes do not approach each other closer than a few kilometers. Rockets for battle on the very short range Sidewinder designed for a minimum distance of one kilometer. A majority of these fights are conducted in much greater distances. For comparison, here is how the target appeared in the "best shooter":

And this is how it should look like in a real fight:

And we are talking about the fight on very short distances. When fighting at long distances to see the enemy with the naked eye is impossible.

It appears on the computer screen point. You are sitting in a fighter cockpit, launching rockets into space, and in a few minutes somewhere there is an explosion, you also do not see.

4. The machine gun can not fire more than a minute

In the movie, it is portrayed like this: you press the trigger, the barrel driving back and forth and watch how the world around you turns into a bloody mess. Here's how it looks in the performance of John Rambo: In the real world in a moment of such intense shooting (unless, of course, would be enough ammunition) his deadly weapons to decayed.

The fact that pulomoty designed for short fire support. The most that is capable of the M60, which is in the hands of Rimbaud - a hundred shots continuous fire. Or about a minute. After that would have to disassemble the machine and change the barrel. Then he could make a hundred more shots, after which he again would have to disassemble the gun and somewhere to take another new barrel.

Now imagine - all this must be prodelyvat during the battle, under enemy fire ...

5. The battle submarines - boredom death

On board the tense silence reigns. Each diver immersed in their task. Suddenly a deafening whistle is added to the steady hum. You spotted the enemy boat! Urgent! We make an evasive maneuver! That's how it looks in "The Hunt for Red October":

Most people know that submarines "see" under water due to sonar. Most people think that the screen at the same time looks like this:

It seems pretty simple. You - in the middle. The enemy boat - a bright red dot. You command the guys who are responsible for you torpedo "Fire!" They shoot ... boom - and there are no more red dot. Again, peace and quiet, and you can drink tea. But…

In fact, the sonar screen looks like this:

Sonars themselves are of two types - active and passive. Active send a signal, and then measured for the amount of time it reaches its reflection. This type of sonar allows you to get information about the enemy important information such as the direction, distance and speed. But 99 percent of the time submarines use passive sonar. They are a plurality of microphones sensitive to water. Coming from these microphones sound of carefully listening to special people. This type of sonar allows you to collect even more useful information - for example, type and class of submarine. Sometimes it even gets to identify the particular ship - only with the help of sound. But to calculate the direction of the other boats with it is difficult.

In those days, when filming "The Hunt for Red October" (1990), even with the help of a computer would take at least 15 minutes of non-stop busy listening to quite accurately determine where to shoot. And it is only in the event that an enemy submarine all this time was so gracious, that did not change the direction and speed of its movement. If not - all efforts to nothing.

So what about the weapons and war - Hollywood still lying. But we, in fact, do not mind - who will pay for a ticket to watch a boring truth?
