- A total of 18 infantry divisions, 10 armored brigades> and affiliated units. The total strength is 560,000.

The newly formed 1st Mobile Panzer Army concentrates the vast majority of the front's armored forces and motor vehicles, and will be used as the core force of the future attack on Siberia.

However, in the previous high-intensity operations, 200 of the 700 armored vehicles belonging to the two armies were scrapped or missing, 300 had to be overhauled, 6,000 cars and tractors were scrapped, and another 2,000 had to be overhauled

Comprehensively considering the needs of future operations and the needs of the front line, the base camp issued a new establishment table for armored units after the formation of the 1st Mecha Group Army. The number of armored vehicles in each armored company (including tank companies and armored vehicle companies) will be increased from 10 to 14, the same as the +.: battalion size, so that the number of armored vehicles in each armored brigade will increase from the original 70 to nearly 100, and the number of automobile tractors will increase to 200. At that time, it was also ordered that the 1st and 4th Panzer Corps under the jurisdiction of the group army will have all the armored vehicles and most of the mobile > available at hand: the Panzer Corps, and let the 3rd A Army complete the conversion of the new establishment first, and most of the officers and men of the 1st and 4th Panzer Corps will return to China by train to receive the new equipment, and then switch to the new establishment at that time.

In this way, before the rearmament and reorganization of the 1st and 4th Panzer Corps. The entire armored combat power of the 1st Mecha Army is only the 3 armored brigades of the 3rd First Army - 3 elite brigades that are fully manned, experienced, morale is high, and the vehicle integrity rate is close to 100%, and they can be mobilized at any time to launch all the combat strength on the new establishment table into battle!

The 1st and 2nd Janissaries of the Janissaries, which were originally part of the Mongol Front, and the 4th Cavalry, which were formerly part of the Northeast Front. The 1st Reserve Army of the battalion temporarily withdrew from the battle line, returned to the country to rest and redress, and focused on strengthening its mobility capability, with the aim of serving as the reserve power of the 1st Mecha Group Army and putting it into the battlefield at the critical moment of decisive victory.

Another armored corps of the Mongolian Front, the 2nd Army of Major General Wen Yu, was transferred to the south by the base camp to change equipment after handing over all its weapons and equipment, and was planned to be integrated into the Indian Front. It is probably impossible to return to the Siberian battlefield.

After the completion of the reorganization of the two major fronts, the first task of the Northern Front was to break through the Ulan-Ude fortress and open the main line of communication to the Baikal front, which was a prerequisite for attacking the Ulan-Ude fortress. In order to quickly complete the rerailing and repair of the railway line between the mainland and Ulan-Ude, the burden fell on the shoulders of the subway troops attached to the Northern Theater of Operations.

After conquering Chita, the base camp decided to form the General Army of the Northern Theater of Railways. The 4th Railway Cluster is a total of 150 railway companies, of which the 1st and 2nd Clusters are respectively responsible for the urgent construction and upgrading of the military railways between the Soviet Union (Mongolia) and Ulan-Ude, and between Manchuria (Heilongjiang) and Chita, the 3rd Group is responsible for the re-railing and repair of the line between Ulan-Ude and the Slyujanka front-line military station at the southern end of Lake Baikal, and the 10th Cluster, which has the largest number of troops, is responsible for the re-railing and repair of the line between Yerofeiyi (Liaoyang Military and Political District, the western terminus of the Haiye Railway) and Ulan-Ude, which is the most important.

The 10th Railway Cluster has 9 railway battalions, a total of 66 railway companies, about 17,000 officers and men, in addition to carrying a large number of professional engineering equipment, it is also equipped with infantry self-defense, including 60 mortars, and the construction site and along the railway line that has been opened to traffic are guarded by the road protection detachment dispatched by the 2nd Regiment Army.

In order to speed up the construction process, the base camp also equipped the cluster with thousands of skilled workers and technicians requisitioned from the Imperial Railway Company and several private railway engineering companies, and granted the cluster the priority of requisitioning prisoner of war labor and distributing Russian civilian labor along the railway. Fair and benevolent food distribution is coordinated with the appropriate amount of gun butts and leather whips", "Let these people who were once ** slaves and now have one foot in the world of freedom and new world work in full swing......

By mid-March, the renovation of about 800 miles of subway between Yerofeii and Chita had been completed, and the cluster had mobilized 12,000 prisoners of war, requisitioned 15,000 local civilians, and received the support of 3,000 skilled Asahi workers and technicians to renovate the last 500 miles of the railway between Chita and Ulan-Ude through the rugged mountainous terrain.

One month later, under the clamor propaganda of "no laborer died, and the king was benevolent and righteous", the Haiye Railway, which connected the port of Vladivostok and the ports of Boli and Hailan Paohe with the inland of the Far East, was finally extended to the city of Ulan-Ude......
