For the next few days, Eva certainly didn't go stupidly to get a ticket.

He was particularly diligent in the days that followed, and he would not leave the Expo Center to be built on the east side of San Francisco all day.

Because it is a military products expo, PTR alone needs at least one airstrip and corresponding spectator seats, so the scope of this area is quite extensive.

There are also various terrains such as deserts, swamps, hills, and lakes to cope with the test of weapons.

While Marchenno and the Russians were busy, Han Huaiyi returned to T Valley, where he had to work with Ford to come up with the design of the mobile gun.

In the era when there were no tanks, it took a long time to think, speculate, and experiment to design this weapon.

But those who have seen tanks can just come to a conclusion.

This is the reason why Truss always thinks Han Huaiyi is weird, and Ford privately says that Charlie is an alien.

Of course, it is not realistic to build a tank like the Tiger in this era.

Han Huaiyi just provided a rough model and asked the engineers at the Ford plant to work backwards.

He came out with the shape of the T series.

This common tank shape in World War II movies directly contains tracks, rotating turrets, inclined armor, commander's observation towers and other elements.

Han Huaiyi threw this thing to Ford's engineers after a ghost drawing, because Truss was busy with the aircraft carrier plan, and because it was a "trivial matter".

But Carttanson, head of design at Ford's plant division, was completely confused when he saw the three-dimensional view.

It was useless for his mind to follow the raptor higher up.

Because he doesn't have that concept in his head.

Han Huaiyi had no choice but to direct the workers and personally participate in the fabrication of the model, and in addition, the overall tank concept map was broken down into parts.

Now, Cattansen finally understood.

He couldn't help but ask suspiciously: "Mr. Charlie, even if this kind of artillery carriage you call a tank is equipped with a large engine, its speed is quite slow, it is not as good as a raptor." ”

"If I ask you to do it, you will do it, and my understanding of war must be stronger than yours." Han Huaiyi was quite unreasonable.

Cartam Sen had no choice but to design and manufacture honestly.

After the ready-made T-Valley automobile production line had the drawings, it took half a week to grind out a large tank model that was not suitable for use.

The reason why it is said that it is useless is because this tank is "beaten" out of thin aluminum sheets.

But the 1:1 ratio of metal is taken out, and it feels completely different.

Looking at the beast lying there, even if it knew that its artillery was fake, it still made those who were facing him feel intimidated, as well as a kind of military industrial beauty.

The concept tank's tracks allow it to adapt to most terrains.

When the concept tank T with a Ford engine installed in front of Sistar, a former army commander, easily ran over the trenches, barbed wire and other barricades made by the soldiers, he excitedly said: "This weapon will be the best friend of the army soldiers!" ”

Sistar's judgment was right, the reason why the tank was able to shine in World War I, especially World War II, was because his natural enemies had not yet really appeared.

Only tanks are used against tanks, so everyone is sharper than whose armor is thick.

So by the end of World War II, the tanks were getting heavier and more ferocious.

Without considering supplies, if any tank from the late stage of World War II, such as the Tiger, were to return to the battlefield of World War I, it would definitely be a massacre.

The concept tank has since been verified by real tests.

Then T-Valley began to make real tanks.

After Han Huaiyi discussed with you, under the premise of considering the power of the current engine, he set the total weight of the tank to 5 tons.

External armor with a thickness of 5 mm was used, a diesel engine with a relatively high level of security, and additional fuel tanks were installed.

In addition, the tank is equipped with an improvised aviation machine gun and a small 85 mm gun.

The tank has a cruising speed of only 20 km / h and a maximum range of 190+20 km.

After formulating the standard, Han Huaiyi named this tank the TA01 type.

On August 11, the first real tank in the military history of mankind rolled off the production line.

In the live-fire test, the 6mm armor successfully resisted the attack of ordinary rifle bullets, and his bevel setting also successfully triggered seven or eight ricochets.

As for the barbed wire that copes with rubber tires and the soles of people's feet, things like thistles have no effect on its track system.

Han Huaiyi immediately ordered to step up production and, through James, applied to the Military Commission for official testing of the weapon.

Because today's production line, which produces one Ford every 15 minutes, can produce this beautiful, but simple-built tank, at a rate of one a day.

So when James and other defense dignitaries arrived at T-Valley on Aug. 25, they already had 15 Type TA01s.

In order to make a deeper impression on the expedition.

Han Huaiyi made arrangements in advance.

He specially invited them to the position of the frontal tank cluster.

At this time, the fifteen steel behemoths painted dark green had already formed a triangle in units of three, and then formed a large triangle as a whole.

Those pitch-black and deep cannon muzzles were so unceremoniously glaring at the military high-ranking people who came to inspect.

"Gentlemen, how do you feel?" Han Huaiyi asked as he stood at the front of the tank queue.

He looked at the well-dressed dignitaries who had never seen the world, and suddenly remembered the picture of a certain weapon test in Iron Man 1.

So the thing opened his arms in a good way, and then snapped his fingers: "Forward." ”

The soldiers did as they were told, and the tanks slowly pushed forward.

"It's a moving artillery array!" James felt the shock and exclaimed, he called back Han Huaiyi and said, "Charlie, where did you come up with so many wonderful ideas to turn him into reality so quickly?" ”

"I'm tired of complimenting me, haha, Lord James and gentlemen, I have consulted with Sistar, and we call the army units equipped with such tanks armoured units. I also proposed a term called army mechanization. You can go to the high platform over there, and we can see the momentum of the tank cluster with the soldiers charging. ”

Sistar testified from the sidelines: "Sir, the momentum of the armored charge is something I have never seen before, and any troops who stand in front of him will be frightened by him." ”

Since they swore an oath, James also trusted Han Huaiyi, so he took the lead and moved to the viewing platform in the distance.

The height of the viewing platform on the hill is about 10 meters, and you can see half of the T valley when you walk up the stairs.
