From the beginning of the school test on the morning of September 11 to the end of the lights out on September 12, excluding a small amount of sleep and rest time, the entire new camp, including Xiao Xuan, was used to test and study different formations.

With the assistance of Xiao Xuan's somewhat ignorant knowledge system, the final result does not seem to have deviated too far. In Europe at this time, the infantry alone was the world of arquebuses and spears, and the cavalry was the world of spear cavalry. Of course, the role of artillery is also increasing. For some reason, chariot soldiers gradually became less popular in Western Europe outside of the Ottoman Empire.

But as far as today's Ming Dynasty is concerned, because of the lack of reliable arquebuses similar to the Japanese iron cannons, even the selected light arquebuses are too much to use. In the end, bows and arrows were less controversial to replace muskets and three-eyed guns, and those junk firearms seemed to have a certain advantage over beginners, but Xiao Xuan believed that even a month or two of training would definitely make bows and arrows stronger than these most rubbish and non-individual firearms.

In terms of the choice of bow and arrow specifications, Xiao Xuan still chose a hunting bow of four or five buckets. Although the "Record of Military Training" said that "first seek the distance and then seek the accuracy", Xiao Xuan at this time still did not relax his vigilance after the Battle of Wumen. Essentially, for at least a few months, the primary potential threat to oneself will not come from abroad, but from within the country, or even from Beijing. The hundreds of people under his command, or the thousands of people who have expanded at most, do not play a big role in the foreign war. But it is a powerful tool to cooperate with the imperial power, strengthen the imperial power, and open up the ability to accumulate wealth by violence. The imaginary enemy of the battle is not a sophisticated rebel army or a strong out-of-town, but a city fox and a rat, a powerful thug, or a rioter who is usually instigated by others. Or something else that is rotten and unbearable for the magnates of Beijing.

To deal with these weak enemies, you don't necessarily need the "one-stone power bow" in Qi Jiguang's books, and it doesn't matter if you are weaker. On the one hand, it is not difficult to find a bow from bow to arrow, and on the other hand, these bows and arrows with an estimated strength of about fifty or sixty pounds are also difficult for beginners who are not too home, and it will take a certain amount of time to effectively use such a bow. If there is a battle in too close proximity, then pick out about half of the protrusions, and you can barely make do with the bow to seven or eight points.

Armed with archers were spearmen, mainly those who were significantly inferior in strength or talent for opening bows. The ratio of archers to spearmen is positioned at 30% each. At this time, Xiao Xuan also discovered another advantage of archers: because bows and arrows are often relatively light, even a bow with sixty light arrows or thirty heavier arrows will not exceed seven catties, compared to crossbowmen or musketeers in carrying secondary weapons. Each archer can also be a melee soldier such as a spear, halberd, javelin, and shield bearer to fight with a spear in a battle array, and carry these weapons without being overweight even if they are wearing armor.

The remaining thirty percent of the soldiers were firearmsmen. Firearms holders can be divided into two categories, one is the gunners. After the actual combat test of tactical thinking, the general cannon weighing about 200 kilograms of 350 kilograms is the most practical. Of course, it is not that this kind of artillery is the best choice, more than 500 kilograms of body barrel combat weight of more than one ton of the last European and American 12-pounder Napoleon cannon, of course, the so-called "general cannon" at the end of the Ming Dynasty more than one street, but the problem is that the casting of heavy artillery has too high requirements for smelting technology, mule and horse traction, etc. In addition to some of the artillery used in the naval division or the heavy artillery such as the "Hongyi cannon" imported from Macao, at this time there were only some old goods in the early Ming Dynasty, and the quality was very worrying. "The ideal is very beautiful, the reality is very skinny" is the second best choice.

In the past ten years since the Later Jin Dynasty raised troops, there was still a sense of unifying the caliber of artillery and selecting suitable shells in the Ming army. In many places, the complicated various projectile artillery pieces have gradually been unified into shells of about seven or eight catties, and only the artillery of this specification has a more stable trajectory and can be fired in a curved manner. In contrast, a body tube of three or four hundred catties is at least able to fire shells at a speed of about half the speed of sound or twice the muzzle velocity of a strong crossbow when the quality of the firearms selected by the Ming army at this time. The accuracy of hits at a safe distance of 100 paces has been greatly increased, and the ability to attack and destroy shield wagons or fortifications has also been significantly enhanced. Even at noon, the effectiveness of such artillery was also very obvious.

Of course, during the Battle of Songjin in history, only about 1,200 artillery pieces of similar specifications participated in the battle. At this time, when the combat readiness was obviously inferior to that of the capital more than ten years later, whether there were one or twenty such artillery pieces in the entire capital was largely unknown, and for the time being, there were only two cannons that the Imperial Horse Supervisor had previously assisted, but the convenience of artillery training was that it was not necessarily based on too many live firings. The ability to measure ranges, load shells or push artillery carts can also be trained by other methods, and "people and other equipment" can be trained.

As for the second and third generals, who seem to be quite widely equipped in the army, in addition to being more convenient in manufacturing at this level, Xiao Xuan finally felt that although this kind of cannon could effectively threaten the hoplites carrying shields, the small cannon of about 30 catties with a body tube like the Tiger Zun cannon or the five or six two projectile Franc machine guns could also achieve this purpose, and it could also be more convenient for single aiming operation, which was better than many hundred-pound body cannons. If you are facing the car shield, you can't be sure that you can go down to the Huzun cannon or the "lifting gun" with a 30-pound specification and weight, and up to the "second general cannon".

Therefore, the change of arms is tentatively assumed that each squadron is equipped with three squadron leader spearmen, three squad archers, and two squadrons each equipped with five "fortified gunners" with a body size of 30 or 40 pounds. The five heavy artillery squadrons and five artillery squadrons were reinforced by the battalion headquarters company, and according to the final assumption, the Guards tactical group of more than 2,000 soldiers and one or two thousand auxiliaries was finally programmed to be five battalions and twenty-five companies, two hundred and fifty short guns, twenty-five general guns, six hundred archers and six hundred spearmen.

The further simplification and harmonization of the establishment system and weapon specifications has also proved to be more conducive to command in practice. What Xiao Xuan didn't know at this time was that under similar conditions, the structure of this arm was much the same as that of the Later Golden Armor Soldiers, except for the lack of cavalry and cavalry, and the establishment system. The most elite "white armor soldiers" are more similar to not sharpshooters or cold weapon braves, but formation-breakers who mainly operate single-man light guns and are equipped with cold weapons.
