Chapter 1732: Fourteen. Yam Liza (1)

An Opel-Blitz light truck roars on the bumpy dirt road of the Principality. After every shock that can give off the internal organs, there will be a scream and scream in the rear compartment, and occasionally Sickness with a sour taste.
This three-ton light truck is one of the hallmarks of the empire. In the last war, the soldiers of the Defense Army who took the lightning truck to the front were one of the totems of the blitz. After the war, the civilian version of this light truck was marketed as one of the empire's main sales products, and the Principality also purchased a part of the configuration for the military.
It’s interesting that the Principality didn’t allocate these trucks to the logistics department or used it to build their own motorized troops. The reason is quite practical-these are imperial products, and once damaged and lost, they can only be purchased from the Empire. The security of supply channels must be considered; in addition, the poor transportation system of the Principality makes them more need tractors than trucks, and the military and civilians need to have good off-road tracked vehicles to transport people or food in winter and muddy seasons; based on the above Demand, the purchase of trucks in the Principality is largely used as a "technical reference (it is said to be a cottage)", but also used to equip the capital military region with better roads, or it is assigned to border patrol units.
Long riding boots, dark blue breeches, brown-green woolen coat, cornflower blue top hat-the officer sitting in the co-pilot position is wearing the most deterrent uniform of the Principality, now up to the military commander, down to The plain-headed people saw that none of the dressed-up guys were indifferent. Especially when the goods knocked on your door with a big soldier, the sound of knocking on the door was the echo of the death knell.
The officer's coat collar was worn with a second lieutenant's square badge, and the armband was sewn on the sleeve. He glanced outside casually. An old farmer on a dirt road just met the second lieutenant. The old man took off his hat and bowed his head to salute.
The power of "Okrana (Delenie Bureau for the Protection of Public Safety and Order)" was further expanded after the outbreak of war, and a series of military operations were frustrated, causing a storm of anti-spyware throughout the Principality. The power of this internal security department has been directly following the Imperial Social Order Security Bureau, and to a certain extent it is still wider than that of its imperial counterparts. The Imperial Social Order Security Bureau cannot intervene in military affairs no matter how fierce it is. Okrana can arrest anyone, including military personnel on active duty, as long as they suspect that this person is a "public enemy", then the fate of this person can be basically determined. Even if there are so many medals on his body that he can be used as a senior general in the dragon scale armor, his legs tremble when he sees the blue cornflower cap.
Meeting an Okrana officer is enough to frighten the old man's courage. Now, in addition to an ensign officer, there are a full group of heavily armed soldiers standing in the back of the truck.
Four Federov automatic guns, two Mosinagan revolver pistols, and three huge water-cooled submachine guns reflect the cold light in the warm sun of early winter.
Ordinary people may be stunned when they hear water-cooled submachine guns. Water-cooled machine guns have heard a lot of them. Both light and heavy machine guns are water-cooled. The submachine gun is water-cooled... what a joke?
This is not a joke, it should be said that it is the product of another combination of Principality-style wisdom and real technical difficulties-a submachine gun that resembles the Austro-Hungarian M1915 submachine gun (in fact, it should be counted as a light machine gun that fires pistols).
Like the old Charlemagne Kingdom, the Principality encountered problems in the metallurgical industry during the design and manufacture of submachine guns. However, the Principality does not like Charlie Man's design that uses dumb bullets to create a burst effect to give the gun body and spring a breathing time. In the view of the designers of the Principality, the purpose of the submachine gun is to use a storm-like barrage to suppress the enemy at short and medium distances and to open the weapon of the breach (this positioning is very accurate). The most important thing about a submachine gun is the rate of fire and the barrage. It can't form a suppressive force. The submachine gun with accuracy and longevity is not as good as the Federov automatic gun that can fire a shot (this is also true). Charlieman's upside-down design completely deviated from the basic purpose of the submachine gun, and it was not desirable at all.
The ideal submachine guns in the minds of the designers of the Principality are like this: they can carry large-capacity ammunition drums, have a high rate of fire, and can sustain fully automatic shooting. The need for maintenance and repair is low.
Those who can meet the above conditions are of course... water-cooled submachine guns.
If the metallurgical process can keep up, the gun designers in the Principality will of course come up with things like PPD or PPSH, but since they can’t do it, they must use some practical methods to solve the difficulties, through choices in certain fields. Meet performance requirements.
This is true of water-cooled machine guns, as well as water-cooled submachine guns.
To put it bluntly, the use of water-cooled firearms is mostly a specific product produced when the metal manufacturing process is not yet mature, and it is only a brief moment in the history of firearms.
The requirements for metal smelting of firearms are extremely strict. After a large number of bullets are fired in a short period of time, the barrel of the substandard performance will reduce the mechanical strength and even deform due to its own high heat. In order to extend the shooting time and accuracy, the gun designers made a large bucket on the periphery of the barrel-this is the water-cooled machine gun.
In the history of the development of firearms in another world ~ EbookFREE.me ~ Because this kind of firearm is very bulky, and after the improvement of metal technology in the later period, water-cooled machine guns were quickly eliminated. Later, only some high-velocity ship-mounted machine guns still used water-cooled structures.
The topic returned to the water-cooled submachine gun of the Principality. The designers of the Principality are of course aware of the advantages and disadvantages of water-cooled structures, but they pay more attention to whether the firearms can meet the needs of the battlefield. Perhaps the increased dead weight caused by the water-cooled structure may be unacceptable to humans or elves, but the soldiers in the Principality are not sharp ears or erect monkeys that can’t be lifted by hands or shoulders. The bears of the Principality of Xiong were a piece of cake. In addition, the extra weight also makes this heavy submachine gun have a melee function after the bullet is hit. In the trenches that cannot be deployed, this "warhammer" is better than the bayonet rifle, and it is rounded. Smash it, whether it is a skull or a scapula, to ensure that it is broken into slag. The peasant soldiers of the Principality Army generally dislike daggers and bayonets, and the use of an axe in their hammers is their housekeeping skill. This stupid and thick black guy is easier to use than a short soldier blade that requires special training.
In addition to the melee function, the performance of this type of submachine gun itself is not bad. The gun fires 7.6225㎜ pistol bullets. Theoretically, it can fire 550-650 rounds per minute. You can use the standard 30-round magazine. If you use a drum, the ammunition capacity can reach an astonishing 160 rounds, and the firepower continuity has been enhanced to almost the level of a light machine gun. As long as the daily maintenance work is done, there is still water in the water-cooled sleeve, and sweeping out a drum at a stretch will not cause a failure.
Carrying a heavily armed soldier, the Lightning truck bounced towards a checkpoint. A border guard sergeant wearing a gray winter coat seemed to find the truck and hurriedly shook the red traffic sign in his hand. Direct the truck to stop.
