Although there are abundant horses, but due to the backwardness of equipment, weapons and agricultural productivity, there are not many professional cavalry at present, most of the cavalry are actually infantry riding ordinary horses, and professional cavalry riding good horses.

Therefore, many cavalry are more likely to use horses as vehicles to engage in mobile transfers to achieve the purpose of rapid mobile transportation.

The march of the infantry brigade is not more than one or two people, or dozens of people walking, the march is thousands of people and thousands of people, accompanied by a large number of heavy equipment, every day to camp and rest, bury pots to make food, often march thirty or forty miles a day, fifty miles faster, the squad travels seventy or eighty miles a day, it is extremely fast. [Note 1]

Because the infantry marched continuously for more than ten or even dozens of days, the violentness of the infantry would damage the endurance of the subsequent march, increase the wounded soldiers, epidemics, and need to be repaired for a long time after arriving at the front line.

And the cavalry is at least eighty or ninety miles, so the meaning of the cavalry at the moment has changed a little, which may be one of the reasons why the tactics and equipment of the cavalry have never been valued and developed.

Of course, if necessary, the infantry can also be used as light cavalry to fight, depending on the decision of the commander and the situation on the battlefield. However, if the judgment is wrong and the handling is not handled properly, the infantry riding the horse encounters the enemy's professional light cavalry, which is bound to be a great defeat.

Such a large north-south span of the Jin Kingdom made Bailiyan believe that the currently known world territory would be larger than expected.

From Pingtang City to the north to the coast of the North Sea, it takes more than a month for the cavalry to march one person and one horse, and it takes more than ten days to reach the border between the Jin and Song dynasties from Pingtang City to the south, which means that from the southernmost border of the Jin State to the North Sea, it takes about fifty days for the cavalry to march slowly, and it takes two to three months for the infantry to walk.

If it is a post station galloping road, each post does not change horses, the fastest day is more than 400 miles of flying newspapers, from south to north also has seven or eight days, and it has to be a straight line distance, in fact, even if it is a gallop road, the official road, it is not straight, which means that from the northernmost seaside, to the southernmost border, even if it is a flying newspaper express delivery, it will take ten days, or even longer, and Pingtang City is located in the middle of the two.

Based on the calculation of the cavalry brigade's marching speed of 60 kilometers a day, it will take 3,000 kilometers in 50 days, and the land area of the Jin Kingdom alone is so vast, and how huge the other great powers are, it is no wonder that for so many years, there have been few dynasties to unify the territory, and the huge territory has greatly limited the loss of communication and military supplies, and it is difficult to maintain the rule of the huge territory for a long time.

Wang Shuojun gathered more than 60,000 cavalry along the way, more than the estimated 40,000, and in addition to the regular soldiers stationed in various places, there was also the "Recruiting People's Army", a kind of self-organized volunteer army. In fact, it was the brothers and relatives in the regular army, and the rebel army was launched.

When the following national military system roughly divides the military composition into seven categories, except for the conscription of the civilian army, the rest are conscription.

As the main force of the armed forces of the following countries, the standing army is also known as the garrison and the garrison. The garrison implements a conscription system, which allows the soldiers to eat food until they die in battle, and there is no military pay, and the family can be exempted from some actual benefits such as tax on ding, land rent, and conscription, but there is no money.

As long as the vassal states have sufficient reserves of grain, grass and military supplies and logistical support, the size of the army can be quickly increased into war in wartime.

The second is the county soldiers and the soldiers and horses of the county and county defending the city, as the first supplementary source of the standing garrison in wartime, but the equipment is inferior and the number is small, the combat effectiveness is poor, and it is stationed in the counties and counties in peacetime, and its functions are similar to the nature of the semi-police and semi-armed police.

As a temporary supplement, conscripts are forcibly conscripted in wartime, and they can be exempted from part of the field rent and taxes and forced labor, and they can get rice and grain pensions for those who die in battle.

As a direct royal force, the forbidden army was small in number, but it was well-armed, and all of them were filled by veterans over the age of 20, and their salaries were higher than those of the garrison, and there were even additional salaries to show the difference in rank and status.

The princes and nobles actually ruled the nations, and the private armies of the protégés of their children were also a force to be reckoned with, ranging from hundreds to two or three thousand, all of which were private armies raised by the princes and nobles. In wartime, you can also go out with the army, and the military exploits you have obtained, under the recommendation of the lord and the princes and nobles, you can even enjoy more rewards, and you can be directly transferred to the army to serve as middle and high-level military positions.

The most important feature of the "recruiting army" is that the recruiting army enjoys the reduction and exemption of grain and taxes during the war, and at the same time enjoys the military merits obtained during the war, and the military merits can be converted into grain and reduced taxes, levy food, and conscription, and during the war, the generals of the conscripted civilian army are controlled, and once the war is over, the conscripted civilian army can be disbanded by itself.

At the same time, the participants of the Recruiting People's Army can obtain tax-free land for 30 years of occupation, so it attracts a large number of people to participate in the Recruitment Army, and many people rush to participate in the war, which is nothing more than to keep a piece of land for themselves.

However, the current system determines that the land theoretically belongs to the king, the big landowner, except for non-rewards, all the fields planted, except for their own grain, all grain is paid as taxes, in a sense, the current land system seriously exploits the enthusiasm of the peasants.

To a large extent, the emergence of the civilian army is a profession that emerged as the times requires from the reform of the military system and the lack of productive forces.

It is impossible to equip everyone with military armor in a huge country, and it is still in the late stage of agricultural bronze and the early era of iron, the productivity is relatively low, the standing army can raise hundreds of thousands, and it is common to mobilize more than one million people to participate in the war in wartime, and one million people to engage in rear transportation and production.

No matter how many people there are, it is a turnip and a pit, and how many weapons are armed, so the agricultural output directly restricts the size of the army.

Of course, the current rate of the riot army is generally not inferior to the situation of Qin unifying China in the late Spring and Autumn Period and the Warring States Period. In a large country like the Jin Kingdom, which has a huge size and a population of more than 30 million, it is almost easy to storm a million soldiers in wartime.

As a regular supplement, the recruiting army basically does not participate in frontal field battles, and the timing of its use is also considered by generals. The nature is more like a death squad, serving as a mobile and field offensive operation, and the more dangerous the mission, the higher the probability of recruiting the civilian army.

It is precisely because of the 30 years of rent-free and tax-free land property that it is far more than the honor and food that ordinary soldiers can obtain in their lifetime. Therefore, although the personnel of the recruiting army are complex, they are basically lifeless, and they can really fight hard for a bite to eat.

As for the deaths in battle, the treatment of the dead of the Recruit Army is no different from that of other non-commissioned soldiers, and their families can be exempted from tax and forced labor for two years or more.

In short, those who die in the country and survive to grab military merits are considered to be earned. Therefore, the number of recruited people's troops is higher in the strong countries, on the contrary, the weak and small countries that always defeat the war have much fewer people's army.

Since it is a death squad, it is basically a life of nine deaths, and no one wants to risk that they will not get any fame and fortune, but they risk death several times higher than that of their ordinary soldiers, and charge into battle. Of course, if the war enters a brutal phase, everyone will have to go to the front whether they want it or not.

The recruiting army that joined Wang Shuo had both cavalry and infantry, and the number was not large, more than 3,000 people. After arriving at the camp of the Northern Army, the Recruiting Army merged with the Beiying Recruiting Army, and the specific number is unknown.

[Note 1]: Regarding the speed of the infantry, it is not too little to only walk forty or fifty miles a day, but it is actually quite a lot. The army carried tens of thousands of people, not tens of thousands of people running marathons to herd sheep, but also carrying tents, rations, equipment, vehicles, livestock, medicines, and so on, all of which were burdens that affected the speed of marching.

The second is durability, you can run a hundred miles a day, but it is impossible to run a marathon every day for ten days and twenty days, the human light infantry created by the 113th Division of the 38th Army of the Volunteer Army runs at a limit speed of 14 hours and 75 kilometers, which can be regarded as the pinnacle of infantry, whether ancient or modern, can not be surpassed. Moreover, the physical requirements of hot weapon warfare are relatively lower than those of cold weapons, so it is unrealistic to run a marathon and then directly engage in white-knuckle combat with knives and guns.

Third, it is possible for the light infantry to throw off the baggage logistics, carry three to five days' rations, and run for 100 miles. During the Warring States Period, Wei Wushu, a typical heavy infantry, could immediately enter the battle after a hundred miles of food and drink, but at that time, the two miles of Qin State were only equivalent to today's 0.7 kilometers, and a hundred miles was thirty-five kilometers, which was really not much.

Finally, the marching speed of the army is closely related to morale, organization, military willpower, military discipline, and the distribution of soldiers' physical fitness.
