Considering the current situation of poverty and backwardness in China, Hu Weidong believed that for a long period of time, the Chinese army would face an enemy that would be stronger than itself in terms of mechanization, firepower, air supremacy, and sea supremacy, so he proposed that it was necessary to focus on the study of mobile guerrilla warfare and urban (or preset defense line) offensive and defensive warfare (this part was mainly to take care of the national army) in the five special terrains that were not conducive to the use of mechanized troops and heavy firepower: mountains, dense forests, swamps, water networks, green gauze tents (and all other fields that could ambush troops).

Among them, mountain warfare attracted Hu Weidong's attention the most, because the other three terrains were not only relatively difficult to overcome, but also relatively more restrictive to one's own people. Since mountain warfare is the combat method that the Red Army, and even later the Eighth Route Army, the People's Liberation Army, and other generations of people's armies are best at, it is undoubtedly the right way to do it in detail and expand the advantages as much as possible.

More than two-thirds of the area in China is occupied by mountains and hills, and the road conditions in China at this time are far from being compared with Europe, not to mention cars in many places, even mules and horses are impassable, so not to mention large-caliber heavy artillery, even the 75mm field artillery, which has always been considered very light, was abandoned by Hu Weidong, and decided to use mountain artillery and mortars as the main infantry support artillery. In short, it must be carried by manpower alone and not seriously slow down the speed of the march.

In this configuration, the lack of suppressed artillery may be a problem, but judging from the characteristics of the people's army's ability to fight guerrilla warfare and movement warfare, it is not a fatal flaw, not to mention that if it is really necessary to suppress the enemy's artillery, it must be a large corps operation, and it is completely possible to ask for friendly support, and there is no need to specifically equip it in the mountain troops to affect the most important mobility ability.

In Hu Weidong's concept, the infantry of the mountain troops should be equipped with as many automatic weapons as possible, including submachine guns, light and heavy machine guns, and in the future, assault rifles and general-purpose machine guns. During the Anti-Japanese War, the biggest threat (especially psychologically) to the Chinese army was their aircraft, so air defense was highly valued by Hu Weidong from the beginning, and the main force began at the regimental level, and there must be a special air defense unit in the establishment. Due to the special nature of mountain troops, small-caliber antiaircraft guns, antiaircraft machine guns, and high-level dual-purpose heavy machine guns have become the main weapons of field air defense of mountain troops. Considering the high altitude of the mountain itself and the complex terrain, under the premise that the troops are well-trained, as long as the tactics are appropriate, the combat efficiency of air defense is still acceptable.

However, just such a configuration will still be a little troublesome when encountering armored troops, especially tanks, after all, even in the mountains, it is not necessarily impossible to encounter tanks, and the later Korean War in history proved that as long as it is used properly, tank units can play a miraculous role in mountains and hills. Therefore, if the anti-armor ability of the mountain troops of the independent division is too poor, it will inevitably suffer a big loss in the future, although the tanks and armored vehicles equipped by Japan during the Anti-Japanese War in history are all thin skin and big stuffing, even anti-aircraft machine guns, and even heavy machine guns (using steel core bullets) can easily break their armor, but who knows if Hu Weidong's crossing will cause a butterfly effect? And the enemy in Hu Weidong's mind is not just Japan

In addition, there are times when mountain troops need to attack fortifications, and anti-armor weapons will also work wonders at that time. Mortar flat firing is a way to do this, but after the transformation, it is impossible to change it back to a normal state, and the armor-piercing ability of mortar shells is not strong, after all, it is only an emergency means. Having the Demoman use a blaster or even a cheaper Molotov cocktail is one option, but the casualties are too great. As for the 37mm battle defense gun equipped by the national army, it is not heavy, but the caliber is too small, but it is almost as heavy as a mountain artillery, and Hu Weidong is really not very interested in it. …,

Therefore, it is obvious that the mountain troops also need a portable anti-armor weapon, and the best infantry anti-armor weapon before the emergence of anti-tank missiles is the bazooka, but with the current capacity of the arsenal, it cannot be done for the time being, and the lack of equipment is on the one hand, mainly because the arsenal often needs to be relocated, and when developing more complex weapons, the efficiency often becomes extremely low due to repeated interruptions. Therefore, Hu Weidong had no choice but to settle for the second best thing, and chose a grenade with a simpler structure and lower production cost than a bazooka

Under the guidance of Hu Weidong, a genius ammunition expert who transcended the times, the arsenal developed grenades much more smoothly than Wu Yunduo in history. Later, after the expansion of the arsenal, Hu Weidong presided over the development of hollow-charged armor-piercing gun grenades (including heavy Scimant grenades that can destroy masonry bunkers) and other deformations in addition to the initial fragmentation grenades, and the bazooka was even more invincible in the face of European and American (relative to Japanese tanks), and the bazooka that was later made was even more invincible, and even the armor of those heavy tanks could not resist. Due to the passage of Hu Weidong, an ammunition genius, this time-space spear and shield contest was out of balance for a while, and it had a far-reaching impact that even Hu Weidong himself did not expect at this moment

Of course, these are only Hu Weidong's ideas for the time being, due to insufficient equipment, he can only write this idea into the "Drill Code", and it was not until later that Hu Weidong was able to form a mountain tiger according to his concept

It must be explained that the reason why Hu Weidong had the leisure to find Sun Liren to cooperate in compiling the "Code of Conduct" was largely because today's independent division was becoming stronger and stronger, which made him feel a lot more relaxed. One of the reasons that cannot be ignored is that the benefits obtained from the capture of Pingxiang are, in a sense, even more than the capture of Yongfeng's battle with Xingan

Pingxiang has a population of more than 400,000, and the proportion of industrial workers is high, the mass base is good, and the economic recession this year, Pingxiang's industrial and mining enterprises have begun to lay off employees and reduce wages (historical facts). Therefore, the expansion of the independent division was very smooth, and Pingxiang was not as poisoned by the scourge of war as the counties in the Soviet area, and the proportion of young people was very high, and Hu Weidong was not prepared to develop it into a base area (the transportation was too convenient), so he recruited as many troops as he could. And Hu Weidong is not as honest as when Zhu Mao came to Pingxiang to expand his popularity, everything is all voluntary, as long as he can let the young people who meet the requirements join, he came up with a lot of ghost ideas, and as a result, the independent division in Pingxiang alone has expanded more than 10,000 people, and all of them are good soldiers
