The Eighth Division of the Japanese Kwantung Army was broken into pieces and secretly infiltrated the Rehe Mountains. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The terrain of the Rehe Mountains is complex and the population is sparse.

It is inhabited by Han and Manchu peoples.

Since it's a secret sneak-in, it can't be discovered.

However, there are always unexpected situations that happen.

The 8th Division of the Kwantung Army is a first-class division.

Even excluding artillery, it was an army of more than 20,000 people.

A typical army armored division is a two-brigade system, with one armored division under one armored brigade and one mechanized infantry brigade.

In addition, the division has an anti-tank artillery regiment (48 6-pounder guns), an armored vehicle regiment (4 squadrons of armored vehicles), an anti-aircraft artillery regiment (54 Bofors 40mm anti-aircraft guns) and two artillery regiments (24 25-pounder guns), as well as engineering units, medical units, etc. The armored brigade is subordinate to 3 tank regiments, 1 mechanized battalion, 3 squadrons under the tank regiment, 3 motorized infantry battalions under the motorized infantry brigade, and the battalion is subordinate to 4 companies. The total number of tanks in the division was less than 200.

Establishment of the Soviet Army

Pre-war period - mid-1940: 12,710 tank corps, 560-600 tanks, 118 artillery pieces. It is organized into 2 light tank brigades, 1 motorized infantry machine gun brigade, and 1 communications battalion. Each light tank brigade consists of 4 tank battalions (54 light tanks and 6 76mm tanks each), 1 reconnaissance battalion, 1 mortar battalion and a number of other logistical administrative units, with a total of 278 BT tanks or 267 T-26 tanks per brigade. The T-26 brigade is a little smaller than the BT brigade, with only 3 battalions, plus a motorized infantry battalion, 1 maintenance battalion, communications/training units; The total number of troops is 2,745 men, 145 T-26 tanks, 56 Spitfire tanks and artillery, 28 armoured vehicles, 482 cars and trucks, and 39 tractors. After the vehicles were fully equipped, most tank brigades armed with T-26 were expanded to 4 tank battalions. Most heavy tank brigades have 136 T28 tanks, 37 BT tanks and 10 Spitfires. There are exceptions, with the 5th Tank Brigade being the only brigade equipped with 94 T35 tanks, 44 BT tanks and 10 Spitfire tanks. At that time, the Soviet Union also had a heavy tank brigade formation, equipped with multi-turret T-28 tanks, which differed little from ordinary tank brigades. The tank platoon of its basic unit had only 3 tanks instead of the ordinary 5. Each tank company has 3 platoons and 1 tank at the company headquarters. The heavy tank battalion consisted of 1 battalion headquarters, 3 tank companies, 1 communications platoon, 1 reconnaissance platoon, and a number of training units. Among them, the communications platoon consisted of 3 BT tanks, 2 BA-20 armored vehicles, 3 radio trucks, 5 motorcycles. The reconnaissance platoon had three BA-20 armored vehicles. The training unit consists of 1 supply platoon (11 trucks), 1 technical platoon, 1 medical platoon (2 trucks) and 1 training platoon (4 trucks). The heavy tank brigade consisted of 3 heavy tank battalions and a number of support units. The reconnaissance company has 1 or more tanks, 2 armored vehicle platoons, and 1 tank platoon.

Mid-1940 - June 1941 War: The new establishment stipulates that one mechanized corps will consist of two tank divisions, one motorized division, one motorcycle regiment, one communications battalion, one engineer battalion, and air force detachments. Each army has more than 36,000 officers and men, 1,031 tanks (including 546 KV or T-34 tanks), 268 armored vehicles and 358 artillery pieces and mortars. Each tank division has 11,343 troops, 210 T-34 medium tanks, 63 KV heavy tanks, 26 BT-7 light tanks, 22 T-26 light tanks, 54 T-36 Spitfire tanks, 56 BA-10 heavy armored vehicles, 39 BA-20 light armored vehicles, 28 field guns, 12 anti-aircraft guns, and 54 mortars. However, there is very little official Soviet information about the internal composition of tank divisions. In May 1940, the Soviet Union also adopted a new armored corps. Approximately 96,785 troops were organized into 1 T-35/KV tank heavy tank brigade, 3 T-28 heavy tank brigades, 16 BT light tank brigades, 18 T-26 light tank brigades, 3 armored vehicle brigades, and 6 separate tank regiments for training and demonstration. The new KV heavy tank brigade consists of 3 tank battalions with a total of 156 tanks (including 39 BT tanks). From 1939 to mid-1940, the Soviet armored forces successively adopted the "tank army-tank brigade" and "independent tank brigade".

From July 1942 onwards, the new tank brigade was formed with 1,038 men, 21 light tanks, and 32 medium tanks. For communication purposes, each platoon commander and company commander's T-34 tank carries a radio station, as well as four RB high-antenna radios, one RSB radio station and four RBS radio stations (the latter being mainly used in infantry battalions) in each brigade. In the first half of 1943, the Soviet armor formation began to be a bit chaotic, first of all, the tank brigade was added to the establishment of 1 anti-aircraft artillery battery (4 37mm anti-aircraft guns, 4 DSHK machine guns). Then, on January 10, NKO ordered an increase in tank and mechanized units. In accordance with the order, the tank corps was increased by one mortar regiment, one assault artillery regiment and one reserve tank detachment, and the size of the fuel transport company was also expanded. Among them, the mortar regiment adopts standard motorized and has two battalions (each battalion has 3 companies and 6 120mm mortars per company). However, the Soviet army's backward communication system still limited the effectiveness of these mortars, with only one radio station per mortar company and two more at the battalion headquarters. The assault artillery regiment was subordinate to 17 Su-76s and 8 Su-122s. The reserve tank detachment consisted of 40 tanks (33 T-34 and 7 T-70), but it was rarely fully manned.

In February 1943, the engineer minesweeper company was expanded into an engineer battalion; In March, the anti-aircraft artillery battery of the subordinate brigade was reorganized into an anti-aircraft artillery battalion (16 37mm guns) attached to the corps, and each battalion was added with 1 communications company. The anti-aircraft machine-gun battery (9 DSHK machine guns) replaced the anti-aircraft artillery battery under the tank brigade. In April, one tank destroyer regiment (20 45mm guns) and one anti-aircraft liaison platoon were added to the tank corps. In May 1943, 1 tank destroyer battalion (12 76mm or 85mm guns) was added, and the self-propelled artillery regiment was changed to a heavy self-propelled artillery regiment with 12 Su-152s each. In August, 2 towed anti-tank artillery units in the tank corps were replaced by 2 self-propelled artillery regiments, one armed with 21 Su-76s and the other with 16 Su-122s.

The U.S. Heavy Equipment Division includes the following units: an armored brigade and a mechanized infantry brigade (infantry brigade), an engineer brigade, a combat aviation brigade, a divisional artillery command, a divisional support command, as well as divisional and divisional companies, an air defense battalion, a communications battalion, a military intelligence battalion, a chemical defense company, and a military police company.

Normally, each armored brigade has a number of tank battalions and infantry battalions, and each tank battalion has four tank companies, each company has three tank platoons, and each platoon usually has four tanks. The formation of the infantry battalion is similar, with one infantry squad for each infantry fighting vehicle. Each battalion has 1 platoon of heavy mortars, armed with 107-mm mortars.

The divisional artillery of the heavy equipment division of the US army consists of three self-propelled howitzer battalions, equipped with 72 155-mm guns and one multiple rocket launch artillery company, and is equipped with nine M270 multiple rocket launchers. Because the US military has strong aviation artillery support, the divisional artillery does not directly support the firepower, the division-level units have independent artillery units under their jurisdiction, and the brigade-level units do not have formed artillery units (except for mortars). When used, the U.S. military often strengthens the division's artillery to brigades in a certain direction for direct support firepower, and sometimes even surpasses brigade-level units to directly provide fire support for battalion-level units.

The logistics support command of the US heavy equipment division usually has an establishment of about 3,000 people, including three forward support battalions, maintenance support battalions, aviation maintenance companies, and material management centers, with a clear division of labor. The maintenance support battalion is divided into a heavy maintenance company, a light maintenance company, a supply and service company, and a transport company, and is equipped with various transport vehicles and support equipment.

The combat aviation brigade under the heavy equipment division of the US military mainly includes a reconnaissance battalion, including two aerial reconnaissance companies, each with a reconnaissance helicopter platoon and an attack helicopter platoon, and two ordinary reconnaissance companies; Two attack helicopter battalions, each containing three attack helicopter companies. Two attack helicopter battalions can provide support for forward combat within a radius of 230 km, and the maneuvering speed can reach 150-200 km/h, which is 3~4 times that of the ground offensive.

The engineer brigade of the heavy equipment division of the US army has three engineer battalions under its jurisdiction, and the division's engineers can independently complete the division's combat engineering support, mine-laying, mine-clearing and other tasks, or quickly construct or maintain roads, blocking obstacles, bridges, and other facilities in the division's combat area. Each engineer battalion has one boat and bridge company and four engineer companies, and is equipped with special engineering equipment such as armored bridge erection vehicles, combat engineering vehicles, and mine-spreading vehicles.

Distinguish from the means of loading. Motorized infantry mainly travels in cars and motorcycles; Mechanized infantry mainly rides armored transport vehicles, infantry fighting vehicles, judging by the way of fighting. The motorized infantry usually maneuvers to the range of the opponent's small-caliber artillery, generally 3 to 5 kilometers away, and enters the offensive starting position after getting off the car, and the car is hidden at this time, and in the artillery fire support stage of artillery fire support (generally 30 to 50 minutes), then the rear movement, the side is expanded into a row of battle formations by the company battle formation, and finally expanded into a group battle formation, at the edge of the distance from the effective range of the enemy's machine guns (generally 400 to 600 meters), it is deployed into a shock battle formation, and the front line of the enemy's defense is attacked at high speed. Implement the final breakthrough. According to the terrain conditions, tanks and armored vehicles can be used to cover, infantry tailgating, or infantry cover, tanks and armored vehicles tailgating and other coordinated action methods to jointly impact the enemy formation, if necessary, the tank in front and the armored vehicle in the rear can be used to coordinate the formation, with the tank mainly covering the armored vehicle and impacting the enemy formation. Mechanized infantry in the above distance, in the march between a little rectification, usually take the tank in front, infantry combat vehicle in the rear of the coordinated action mode, to achieve the "while rushing" requirements, when necessary, can also take the infantry to get off the vehicle to support the tank battle, foot to support the tank impact of the coordinated action mode, to complete the impact breakthrough task. The weapons of the battle are different. Motorized infantry mainly uses individual weapons; Mechanized infantry, on the other hand, mainly uses vehicle-mounted weapons, such as artillery, anti-tank and anti-aircraft missiles, vehicle-mounted mortars, grenade launchers, etc., while individual weapons are secondary. The communication command is different. Motorized infantry mainly uses infantry command methods, such as passwords, flags, and infantry radio. On this basis, mechanized infantry mainly adopts vehicle-mounted radios and infantry-tank cooperative radios. Comparatively speaking, the organization and command of mechanized infantry and tanks are more complicated.

The combat aviation brigade under the heavy equipment division of the US military mainly includes a reconnaissance battalion, including two aerial reconnaissance companies, each with a reconnaissance helicopter platoon and an attack helicopter platoon, and two ordinary reconnaissance companies; Two attack helicopter battalions, each containing three attack helicopter companies. Two attack helicopter battalions can provide support for forward combat within a radius of 230 km, and the maneuvering speed can reach 150-200 km/h, which is 3~4 times that of the ground offensive.

The engineer brigade of the heavy equipment division of the US army has three engineer battalions under its jurisdiction, and the division's engineers can independently complete the division's combat engineering support, mine-laying, mine-clearing and other tasks, or quickly construct or maintain roads, blocking obstacles, bridges, and other facilities in the division's combat area. Each engineer battalion has one boat and bridge company and four engineer companies, and is equipped with special engineering equipment such as armored bridge erection vehicles, combat engineering vehicles, and mine-spreading vehicles.
