On the European continent, the great war between the Monarchical Entente and the three major powers of the Revolutionary Alliance undoubtedly made the development of the Han Empire extremely comfortable!

The development of industry and the research and development of weapons science and technology, everything is carried out in an orderly manner, because the Han Empire sent 100,000 people to Europe to participate in the war, joined the Monarchical Entente, and the embargo on raw materials carried out by the British colonies on the Han Empire was completely canceled, Zhao Dutian could take the tax to squeeze the Native Americans and whites, and buy military raw materials from colonies around the world!

When everything went well, in the fifty-eighth year of the Han Dynasty one year after the Dahan was finalized, the truly practical 75-mm field gun was freshly baked!

The maximum division of the gauge is 280 meters in elevation

This field gun is a land combat model improved from the guns on the Zhenyuan and Dingyuan, with a maximum range of 6,000 meters to ensure the completion of all battlefield forms in this era!

As for the mountainous jungles with complex and changeable terrain, Zhao Dutian handed over the individual grenadiers that were about to be developed!

It's not that Zhao Dutian doesn't want to develop a special mountain artillery, in fact, the difference between a mountain artillery and a field artillery is still very big!

To put it simply:

Mountain artillery: short barrel, light weight, short firing range, easy to maneuver, suitable for mountain combat artillery, belongs to light howitzers. Pen & Fun & Pavilion www.biquge.info

Field artillery: long barrel, heavy weight, long range, less mobile than mountain artillery, suitable for field artillery, generally a combination of heavy howitzers and cannons.

If Zhao Dutian faced an enemy with the same armament, the weapon of mountain artillery was naturally indispensable, but in the face of a group of enemies with mixed weapons of cold and hot weapons......

There are powerful 75-mm field guns that are enough!

Of course, there is still a lot of room for improvement in the 75mm field gun developed by the Han Empire, but this data is enough for today's era, and Zhao Dutian has no plans to assemble this expensive 75mm field gun on a large scale!

With the industrial strength and economic situation of the Han Empire, maintaining an artillery group of dozens of 75mm field guns is already the limit!

This 75mm field gun is only used for large-scale battles, and Zhao Dutian does not plan to promote it throughout the army, for the simple reason that the Han Empire cannot afford to play it!

The real killer features developed by Zhao Dutian are grenadiers and grenades that can be used as mortar shells!

THE ALIAS OF THE GRENADIER IS ALSO CALLED THE ULTRA-LIGHT MORTAR, THE CALIBER IS BELOW 50MM, CARRIED BY A SINGLE SOLDIER, EACH GRENADIER ONLY NEEDS TWO PEOPLE AT MOST TO EXERT MAXIMUM COMBAT EFFECTIVENESS, AND EVEN A SKILLED SOLDIER CAN RUN AROUND WITH A GRENADIER TO CARRY OUT ACCURATE POSITIONING BOMBARDMENT OF THE ENEMY!

Grenadier Range: A weapon between a grenade and a bazooka. Ammunition: 2 ammo. And the ammunition of the grenadier can be selected as the point of impact for throwing butterfly mines (a type of light anti-infantry mine) directly to form small mines, which will be of great use in defensive warfare. It is possible to set the time for which the weapon is set up. Attack: Parabolic attack. Pendant: You can add sights to lengthen the gun body to increase the attack range.

When firing, the shooter pulls the firing lever first, and then the ammunition is loaded by the ammunition hand from the barrel mouth to complete the installation of the ammunition. Hold the canister with the left hand, turn the handle according to the target distance until the adjustment lever reaches the corresponding length, the shooter takes a rough aim through the aiming line, pulls the belt on the firing machine, and fires the bottom of the explosive to shoot the grenade out.

Since the propellant at the bottom has not changed, the angle of the grenadier is adjusted to determine the firing distance and aim at the target, so only an experienced grenadier can accurately hit the target.

However, Zhao Dutian was not facing World War II troops who would be hidden and lurking, and there were no high-value machine gun points to knock out with grenadiers, so the requirements for the operation of grenadiers were not high.

Compared with this shortcoming, the two big advantages of the grenadier canister are enough to make up for it!

1. Lightweight, easy to carry, provides timely fire support: This grenadier is less than 3 kg, which is much lighter than the weight of a rifle, making it ideal for individual carrying.

The grenade is only 0.45 kilograms, the ammunition bag is only 3.6 kilograms for eight rounds, and the entire combat system with grenadiers is less than 7 kilograms, which is much lighter than a Czech light machine gun. Due to their light weight, grenadier crews will not be able to fight with front-line infantry in time due to heavy loads like mortar crews or heavy machine gun crews. In real combat, grenadier groups can even charge with the infantry.

2. Good power and low cost: Generally speaking, the killing radius of the grenadier is about 5 to 8 meters, and a grenade can kill and injure dozens of people if it falls in the crowd, which is still good for a 50 mm caliber.

What Zhao Dutian cares about the most is that the cost of a grenadier is cheaper than a Dahan rifle!

Ordinary infantry grenades are also extremely cheap. Such a price is simply too cheap for the good power of the grenadier!

Especially today's Han Empire's industrial production capacity is not high, and the national economy is still very fragile.

It can be said that before the popularity of tanks and armored vehicles, the grenadier will become a cheap and high-standard iconic weapon of the Han Empire!

Zhao Dutian plans to give the troops after the military reform in the future, and issue grenadier weapons to the squad soldiers!

While Zhao Dutian was working hard to develop grenadiers and produce 75mm field guns, the British Empire, as the region least affected by the revolutionary war, had begun to quietly install the breech-loading rifled guns they had developed independently!

The breech gun is not a technical problem for the European powers, and the European powers, which have always attached importance to science, have a good foundation in themselves, and rifled gun technology has appeared as early as two hundred years ago!

The reason why the European powers did not make efforts to develop breech guns was mainly due to the hindrance of conservative concepts and the lack of confidence in the performance of breech-loading guns!

In the American War, the shocking reversal of the Dreiser rifle of the Han Empire woke up the entire European continental powers, but the revolution came too fast, and the European continental powers did not wait for the development of the breech-loading rifled gun, and the entire social system was destroyed, even if the countries that were not occupied by the revolutionary army, they were struggling to support, and they had no energy to engage in scientific research at all, only Britain relied on the English Channel, the first to develop a breech-loading rifled gun!
