The independent regiment is a very special combat unit, ranking higher than the ordinary regiment. It is not under the jurisdiction of the divisional headquarters, but often directly under the military headquarters. The organizational system of independent regiments is also very complicated. The number of independent regiments varies greatly. There are more than 2,000 independent regiments with strong strength and less than 500 independent regiments with weak strength. In fact, independent regiments have 2-5 battalions, or 5-10 brigades. Some independent regiments set up brigades directly instead of battalions. We can look at the situation of the independent regiment, a very special combat unit, from three aspects in history. First, the Ye Ting Independent Regiment has jurisdiction over three infantry battalions and a service team directly under it, with a total of about 2,000 people. Although it is an independent regiment of the Fourth Army of the National Revolutionary Army, it is actually an armed force directly led by the Party. In mid-November 1925, the National Revolutionary Army was reorganized. The Guangdong District Committee led by Chen Yannian, after striving for the consent of Li Jishen, commander of the Fourth Army, established an independent group led by the party, headed by party member Ye Ting. Ye Ting was called back to Guangzhou from the front line of the Eastern Expedition as the 34th leader, and went to Zhaoqing for preparatory work. Based on the armored motorcade, the independent regiment was expanded in Zhaoqing, Guangdong Province, and was originally called the 34th Regiment of the 12th Division of the Fourth Army. In addition to Liao Ganwu, the representative of the armored motorcade, being transferred to the Director of the Political Department of the Fourth Army, the captain Zhou Shidi and three platoon leaders, the secretary, the squad leader and 100 soldiers were transferred to the 34th Regiment as the backbone. In the spring of 1926, the 34th Regiment broke away from the organizational system of the 12th Division and was directly led by the Fourth Army. It was renamed the Independent Regiment of the Fourth Army and became a revolutionary armed force under the direct leadership of the Party. The independent regiment has three battalions and directly affiliated service teams, with a total of more than 2,000 people. It is mainly composed of three parts: the armored motorcade originally attached to the Marshal&;s Office, some backbones transferred from the Whampoa Military Academy, and peasant activists recruited from Guangdong, Guangxi and Hunan. This is the first unit formed by the Party members, with distinctive &”;Party Army&”; characteristics. Independent Regiment, headed by Ye Ting, is also called Ye Ting Independent Regiment. Although it is an independent regiment of the Fourth Army of the National Revolutionary Army, it is actually an armed force directly led by the Party. The appointment and removal of cadres above the platoon level, the replenishment of troops and major military and political training plans are all decided by the party and are not bound by the Fourth Army. Most of the cadres above the company level are party member and Communist Youth League members. Party branches are established in the whole regiment and party groups are established in each battalion. Independent regiments are fully developed and the principle of unity between officers and men is implemented. The economy is open, and cadres are not specialized. It is said that the independent regiment had only one horse, and when it marched, Ye Ting gave it to the sick and wounded, and climbed mountains and waded with the soldiers. Ye Ting Independent Regiment won the title of &”;Iron Army&”;. In April 1926, Wu Peifu appointed Ye Kaixin as &”;Commander-in-Chief of Xiang Army&”; to attack Tang Shengzhi. Soon, the Eighth Brigade of the Seventh Army of the National Revolutionary Army and the Ye Ting Independent Regiment under the jurisdiction of the Fourth Army, as vanguard forces, sent troops to help and were defeated by Wu Peifu reinforcements, and retreated to the Tang Shengzhi Department of Hengyang, which started the Northern Expedition. Among the eight armies of the National Revolutionary Army, party member is the largest in the Fourth Army, and Ye Ting is the independent regiment, which is the most effective one. Later, the Ye Ting Independent Group arrived in Anren County, Hunan Province, and repelled.Direct line advancing towards Anren. The enemy defeated you county and Chaling, and the independent regiment pursued them and occupied you county. After entering Hubei, the Northern Expeditionary Army decided to attack with tunnel warfare, and Ye Ting personally directed the tunnel operation. He finally commanded the independent regiment to occupy the Snake Mountain and first entered Wuchang City. The Independent Regiment sacrificed 191 officers and men in this battle. The Party branch of the Independent Regiment decided to build the tombs of the soldiers and soldiers who besieged the city in Hongshan, Wuchang. The tombstone was engraved with &”;the spirit is immortal&”; and &”;the blood of martyrs, the flower of doctrine&”;. The blood of the martyrs was cast into famous sentences such as &”;the honor of the iron army&”;. This martyr&;s tombstone has become a historical testimony of the party members and revolutionary soldiers who were brave and brave in the Northern Expedition and were not afraid of sacrifice. Second, many regimental units of the Red Army will also set up independent regiments. The &”;Independent Regiment of Western Hunan and Hubei&”; of the New Sixth Army is more famous than that of the Xiangbei Independent Regiment of Dahongshan. During the Long March, the &”;Independent Regiment along the River&”; was cancelled by the guerrillas. Before the establishment of the Hunan and Hubei Provincial Party Committee, it was also announced that the new Sixth Army would be reorganized and military school students would be organized to form an independent regiment of Western Hunan and Hubei, headed by Duan Dechang. This independent regiment of the Red Army governs the 1st, 2nd, 3rd Battalion and a spy battalion. Chen Huashan, Battalion One, Chen Guangming, Battalion Two, Yang Jiarui, Battalion Three, and Dong Guozhou, Battalion Special Agent. Song Panming conveyed the instructions that the 26th Division of Red Army insisted on long-term guerrilla warfare and never left Dahongshan. In Dahongshan, the guerrilla corps in northern Hubei, the guerrilla brigade in Zhongxiang County and the guerrillas in Xiangbei counties transferred to Dahongshan were compiled into Xiangbei Independent Regiment. This independent regiment has jurisdiction over 3 battalions, 1 guard company, 1 pistol company and 1 cavalry company, with more than 1,200 guns. Later, the guerrillas in northern Hubei also organized the Xiangbei Independent Regiment, and still carried out activities in the name of the guerrillas in northern Hubei. Relying on Dahongshan, Xiangbei Independent Regiment started from Yingcheng, Jingshan and Tianmen in the east, stopped at Jingmen and Dangyang in the west, and reached Yicheng and Suixian in the north. Hong Jiu division commander Zhong Bingran and political commissar Zhu Shaotian personally came to Ganxi, Shangba and Qitan to mobilize the masses, establish the Soviet Union and organize workers and peasants&; armed forces. After Hong Jiu Division left, a team led by Red Army cadres He Bingyan and Hu Hongsheng continued to work, and more than a dozen guerrilla brigades were formed successively. Soon, the guerrillas were reorganized into &”;Independent Regiment along the River&”;, with He Bingyan as the head and Hu Hong as the political commissar. After reorganization, the independent regiment had 10 brigades, each of which was divided into several squadrons, with about 1,000 personnel. There are more than 10 guerrilla brigades in the independent regiment along the river. Third, during the war, the guerrilla independent regiments were the most famous. The organizational system of these independent regiments was complicated, and the situation varied greatly from place to place. In March 1945, the troops were reorganized, and the organizational system of the county brigade was expanded. It was renamed Xiajin Independent Regiment, with Ma Lichao as the head, Li Kaidao as the political commissar, Ran Yilin as the deputy political commissar and Zhu Kui as the acting chief of staff. The Independent Regiment has jurisdiction over six companies. Except for the first, second and fourth companies of the county brigade, the 13th squadron of the Canal Brigade led by Ma Lichao (4 platoons, including 1 Huimin platoon, with a total of 120 people) is organized into three companies. Jingbo Liu&;s five-district squadron and six-district squadron were co-edited into five companies, with a total of nearly 1,000 independent groups. With the support and help of the fifth detachment of the New Fourth Army, the Huaibao Independent Regiment was established, and the main commanders were all composed of five detachments.Cadres at or above the company battalion level. By November 1941, the Huaibao Independent Group had grown to more than 700 people. In January, 1942, the Huaibao Independent Regiment administered five infantry companies with a total of 550 men, all of which were well equipped. Since then, every year, some backbones of Huaibao Independent Regiment have been added to the main force of the New Fourth Army. At the beginning of September, 1945, Xia Shangzhi, Commissioner of the First Administrative Supervision Office of Beiman Region and commander of the first column of Nenjiang River, led his troops to Guoqian Banner, and with the help of the Soviet army, he received the horse guns, wild guns, mountain guns, light and heavy machine guns and a batch captured by the Soviet army. After formal military and political training, young Mongolian soldiers improved the military and political quality of commanders and soldiers, laid the foundation for later severe tests, and trained a group of backbone forces for establishing an independent regiment of Mongolian cavalry. Later, the superior decided to divide the 3rd Regiment and 2nd Battalion of Changbai Column, the former Mongolian Army of Guoqianqi, from the 3rd Regiment of Changbai Column, and co-edit it with Guoqianqi Public Security Team and Security Team to form the Mongolian Cavalry Independent Regiment of Jijiang Military Region. After fierce struggle and complicated work, the co-editing work was basically completed. The Jijiang Military Region&;s &”;Mongolian Cavalry Independent Regiment&”; has a total of more than 1,100 people, including more than 300 former Mongolian Revolutionary Army soldiers, more than 10 grassroots cadres in Changbai Column, and more than 800 security guards and security guards. Establishment of regimental headquarters: staff office, political office, supply office, health team and guard company. To sum up, Ye Ting Independent Regiment has jurisdiction over three infantry battalions and one service team directly under it, with a total of about 2,000 people. Many regimental units of the Red Army will also set up independent regiments. The &”;Hunan-Hubei Independent Regiment&”; of the New Sixth Army and the &”;Xiangbei Independent Regiment&”; of Dahongshan are more famous, and the &”;Independence Regiment along the River&”; during the Long March is composed of guerrillas. During the war, the most famous independent regiments were guerrillas. The organizational system of these independent regiments was complicated, and the situation varied greatly from place to place. Generally speaking, there are more than 2,000 independent groups with strong strength, but less than 500 independent groups with weak strength. In fact, independent regiments have 2-5 battalions, or 5-10 brigades. Some independent regiments set up brigades directly instead of battalions.
