Lying solemnly 400 meters away from the half-body target, the camouflage uniform was already soaked with stagnant water on the ground.

Fortunately, the rain stopped, and the light was much better than when it rained before.

The valley was washed by rain once, and even the air was filled with the scent of weeds.

However, the cold wind blew in the mountains, blowing on the wet camouflage uniforms, making the body temperature shiver.

When solemnly lying down in the firing position and looking at the half-length target in the distance from the notched door and pillar crosshair of the Type 81-1 automatic rifle, he understood what a marksman was.

The eight veterans who got the qualification of sharpshooters lying next to him were definitely not as simple as they imagined.

Because, the target is almost gone!

And outside the firing line, all the officers and soldiers were focused on the solemn body.

"The direction of the wind...... Boy, the wind is ......"

Zhang Jianxing pinched his chin hard, touched the stubble of his beard that was harder than the hair on the brush, and kept chattering about a key factor.

Wind.

Now, Majeres is 400 meters away from the half-body target.

What distance is this?

According to the elements of the Type 81-1 automatic rifle, the maximum direct firing distance of this gun is only 400 meters, and the side firing distance will reach 500 meters.

Now this shooting mode is equivalent to taking both the gun and the person to the extreme!

"Company commander, this is the assessment standard for a special marksman shooter." Yin Xiancong on the side couldn't help but say: "Solemn...... Will it work? ”

Zhang Jianxing was a little unhappy and said: "What can I do, the cow was blown down by himself, Deputy Division Commander Cai is here, can't I go up to stop it?" This guy! It's this dick temperament! Never know how thick the sky is. ”

Zhang Jianxing's biggest concern was that Zhuang Yan had never tried to shoot at a half-body target at 400 meters.

Because the Type 81-1 automatic rifle is a mechanical sight, although the position of the door is designed with a ruler, there are a total of 5 gears, and the shooter can install 1-5 levels of rulers according to the distance of 100, 200, 300, 400, and 500 meters, so Zhang Jianxing is not very worried about the high and low firing angles.

What worries Zhang Jianxing the most is his solemn understanding of the wind.

That's right.

It's the wind.

Shooting seems simple, but it will never be a random gun in the movie that can kill one with a single click, then it is a god, not a human.

Even the best snipers tend to stick a piece of sticker on the stock of their sniper rifle with various correction formulas printed on it.

This is the extreme.

Why is it complicated?

Taking the wind as an example, there are three criteria for PLA top shooters to judge the direction of the wind - weak wind, moderate wind, and strong wind.

In terms of direction, there are crosswinds, crosswinds, and oblique winds.

In terms of intensity, there are weak winds, gentle winds, and strong winds.

Among them, the one that most affects the trajectory of the shot is the crosswind.

The standard for transverse weak winds is 2-3 meters per second, which is equivalent to a second-class wind; The standard for horizontal wind is 4-7 meters per second, which is equivalent to three to four winds; The wind speed of the horizontal strong wind is 8-12 meters per second, which is equivalent to five to six winds.

Snipers usually have a small wind speed meter in their hands, which can be used to easily measure wind speed.

However, the PLA's top marksman needs a lot of experience and talent to hit a target 400 meters away in windy conditions without any assistance.

If there is no wind speed meter, then it depends on visual inspection and perception.

How to perceive?

When the wind is weak, the human feeling is that the face and hands feel a little wind, and the feeling of the wind is that the wind is obviously felt, and a slight whining wind can be heard, but when facing the wind, you can open your eyes; Strong winds are the ones that feel significant resistance to standing or walking head-on, and are dusty, making it difficult to keep your eyes open to the wind.

Not only human perception, but also more than a dozen common objects and plants can make an estimate of the wind force.

For example, when the wind is weak, the grass is slightly moving, when the wind is blowing, the grass is easy to bend, and when the wind is strong, the grass is almost blown to the ground.

Then there are the trees, and when the wind is weak, the shrubs and thin branches and leaves move slightly and rustle; When the wind blows, the upper edge of the shrub will swing, the thin branches of the tree will be bent, and the leaves will shake violently; Strong winds are the easiest to tell, because even the slightest bit of tree trunks will blow and bend, and thick branches will shake violently.

Not only these, but also flags, smoke, waves on the sea, fishing boats, or heat waves steaming from the ground in desert areas, etc., can all determine the level of the wind.

However, based on experience, the sharpshooters of the older generation of the army used the Japanese wind as a criterion for taking value, and thus summed up a mantra: the wind has a size, and the wind is compared. The wind can open your eyes, your ears hear the sound of whistling, the smoke becomes an oblique angle, the grass bends and the branches shake, the sea rises lightly, and the sails are tilted to one side. Strong winds are stronger than it, and weak winds are smaller than it.

Once there is wind, it must be corrected, and there are actually several formulas to calculate the impact of wind on the trajectory, including the formula for calculating the hit rate, the formula for modifying the cross wind, and so on.

There is an old saying among the local shooters: 1200 don't need to be repaired, 300 aim at the ear line, and 400 aim at the edge.

However, this is only a little judgment in the case of cross-and-wind (wind speed of 4 m/s).

Moreover, it is also an extremely general judgment and is not accurate.

This is because the correct correction mantra for the special marksman in the unit to use a mechanical sight to shoot at a target within 400 meters under the conditions of horizontal winds is - 100 do not need to be repaired, 200 aim at the ear line, 300 aim at the edge, and 400 edge to the edge.

Every prime marksman, commonly known as a marksman, has to memorize everything from submachine guns and automatic rifles to light machine guns to heavy machine guns.

If you can't carry this thing, let him get out, no one will believe him if he says he is a marksman!

Because this is something that every PLA elite army veteran must be able to memorize.

Take 500 meters as an example, the environment is weak wind, and the wind is blowing from the right side, how to correct it?

A skilled shooter will immediately make calculations in his head -

(1) If the target distance is 500 meters, the ruler is set at 5. According to the formula, the correction amount of the wind is: 5-2.5=2.5.

(2) The wind speed of 2-3 m/s is a weak wind, and the calculation formula based on the wind is reduced by half as required;

(3) The wind blowing from the front right is an evil wind, and the impact of the evil wind on the ballistics is halved;

(4) The final correction is: 1.25-1.25/2 is about 0.63 (human body).

Then: When aiming, the aiming point should be corrected to the right by half a human body.

This is the calculation of the top shooter.

He has never practiced the four exercises solemnly, let alone learned these correction formulas, he is just a rookie.

Zhang Jianxing knew all this very well, so he was worried.

Of all the people present, no one believed that Zhuang Yan could actually hit a half-body target from 400 meters away, because it was a bit magical.

The recruits all craned their necks, waiting for the solemn shooting, and as fellow recruits, they expected that solemnity could fight for the recruits.

The veterans watched the excitement mostly, and they all hoped that the eight veteran marksmen on the shooting line could let the new soldier know that Ma Wang Ye opened a few eyes.

Three bullets, time limit 10 minutes.

Minutes and seconds passed, and everyone waited silently for the gunshots to go off.

Phew-

After a long silence, the shooters on the firing line finally opened fire.

Zhang Jianxing saw that the solemn gun shook slightly, and a cloud of light smoke came out.

He knew that the kid had shot.

As long as it hits, the opposite target rod will be raised and placed on the bull's-eye, indicating that the hit is effective.

Everyone held their breath, and everyone's attention was on the solemn 7th target.
