"Old He, you can't go, it's too dangerous."

Hearing Qin Zhenhua's greeting, He Lao was the first to walk over with a smile, and was about to get into the car, he was the biggest here, he didn't get on it, and others were not easy to move, but when he went up, the guards who followed him began to block it.

The danger this time is very great, the big guy is over, the distance is so close, what if the shell misses? At this time, he didn't know what the harm of that special alloy bullet was, [college student] otherwise, he would definitely not let He Lao pass.

Now, hearing the guard's words, He Lao shook his head: "It's okay, it's okay, Zhenhua has already made arrangements, isn't it?" ”

"Yes, please rest assured that we will definitely protect the safety of the leaders."

"You do things, I don't worry." He Lao said, and the first one walked in.

The first one to go in, of course, had to sit in the commander's place, there, there was a periscope used by the commander, the field of vision was the widest, and, moreover, the most comfortable, as for the people who came in later, they could only sit on the two rows of seats on both sides of the back.

The space inside is still good, after all, this wheeled infantry fighting vehicle, the engine is in the front, so that the space behind is very open, but the height is a little depressing, and after entering, you can only bend down and can't stand up straight.

"Welcome to Battlefield Taxi." Qin Zhenhua said playfully: "Now, please sit tight and hold on, we are going to start!" ”

Wang Erzhu in front of him, driving in person, he started the engine, and the familiar clatter of the high-pressure oil pump sounded, gear, loosened the clutch, Wang Erzhu drove as slowly as possible, so that it could be more comfortable.

However, He Lao was not happy.

"This car is too slow, isn't it? Even our 63 armored vehicles can't compare. He Lao said.

"Then everyone should fasten their seatbelts." Qin Zhenhua shouted: "Now, drag racing has officially begun!" ”

The engine roared, Wang Erzhu quickly stepped on the throttle, shifting gears, if it was on the side, you can see that when he shifted gears, he completely relied on speed and throttle to control, and there was no need to step on the clutch at all, and the gear began to rise rapidly, second gear, third gear, fourth gear, and then, with a snort, switching between high and low speeds, to the high-end area, roared again, fifth gear, sixth gear.

The ground of the shooting range is relatively flat, the trench of the crawler is not very deep, and the six tires with thick off-road patterns are crushing the ground of the shooting range, rushing at high speed, and those who are left behind outside are all stunned.

"I'm afraid this speed is enough for forty, right?"

"At least fifty!"

"Wow, hit the direction so quickly, aren't you afraid of overturning?"

There were bursts of exclamations behind them, and in their attention, the off-road tires of the car almost had a lateral side slip, but the body was still stable and did not leave the ground, so it completed a sharp turn, which was very beautiful.

Since everyone wants to feel it, let's feel it! Anyway, it can also leave a deep impression on everyone.

With such an idea, the 551 infantry fighting vehicle made a big circle around the shooting range, which really made a show.

Inside the car, some people were already pale, and some people were covering their mouths.

He Lao was very interested, and when he made the sharp turn just now, He Lao obviously cheered, not bad, not bad! Back then, when I was fighting, fighting in the south and in the north, sitting in a gas car, this is the feeling, that bend, it's really urgent, just turned around, a shell fell on the side, if you don't turn, you will be gone at that time.

Now, thinking back to the past, at the same time, the performance of this car is also full of praise, driving in the army, it is like a tiger descending the mountain, which can reflect the real performance of the vehicle!

He Lao sighed like this, and at the same time, the car finally stopped slowly, and at this time, it had reached a hundred meters away from the side of the target.

"Attention, activate the overpressure three-proof system." Qin Zhenhua shouted.

A buzzing sound came from underfoot.

As a military vehicle, it needs to pass through various complex terrains, and also needs to pass through nuclear, biological and chemical areas.

In the past, gas masks were mainly worn, but this thing was too uncomfortable to wear, especially in the summer, and the gas masks made of rubber were fastened on the face and could make people faint.

So, then it all depends on the on-board system.

If you want to completely seal the tank, infantry fighting vehicle, it is not breathable, it is impossible, besides, if it is not breathable, the people inside will suffocate.

The outside air can't breathe because it is polluted, so the car body carries its own filter device, which can filter the air out, and most of the filter devices are activated carbon, which has a special smell when breathing.

At the same time, the filtered air, after entering the car, is pressurized, yes, the pressure inside the car is higher than the outside of the car!

What are the benefits of this?

The convection of the air cannot be formed, and the outside air, through those possible gaps, cannot enter, because the pressure inside is strong, and the air inside is flowing outward through those gaps, and the air is flowing outward, and the outside air naturally cannot enter.

This creates an isolated environment inside.

Everything was ready, the periscope was adjusted a few times, and the people behind observed the target over there through the observation window, and then, Qin Zhenhua made a voice on the radio: "The 551 armored car has been prepared, and the test can begin." ”

Okay, you guys are finally done with the toss, Xie Huimin here is also relieved, and then, the self-propelled anti-tank gun started to move.

Since it is self-propelled, of course, it cannot be left in place, so there is also a suspicion of cheating.

The 520-horsepower diesel engine in front rumbled, six pairs of load-bearing wheels gurgled and turned, and the huge body swayed forward.

The target three thousand meters away was constantly approaching, two thousand five hundred meters, two thousand meters, one thousand five hundred meters, and at this distance, finally, the hull stopped, and at the moment of stopping, the barrel shook significantly downward.

"Armor-piercing bullet four, load!"

The loader in the back, holding a specially marked armor-piercing bullet, put it on the semi-automatic loader, which rattled and stuffed the shell into the chamber with a clatter.

At the same time, Xie Huimin personally aimed up, he held his breath, adjusted several times, and finally, stabilized his mood.

"Aim and fire!"

"Boom!"

On the muzzle, a flame rose, and the entire self-propelled gun, under the action of this recoil, trembled violently, and the parts of the track and the ground were desperately pinning each other down, hindering the rear movement of the hull.

A bullet core, in the midst of flames, flies forward!
