The Ho-103 is a variant of the Japanese Type 1 short-recoil operated heavy machine gun. The design was based on the M1921 Browning and chambered for the Italian 12.7x81SR cartridge. Compared to contemporaries such as the M2 Browning, the Ho-103 weighed less but had significantly lower muzzle velocity and projectile mass.
+
The '''MG 3A1''' is a German 7.62 mm General-Purpose Machine Gun (GPMG). The MG 3A1 is a post-war derivative of the [[MG 42 (7.92 mm)]] machine gun, re-chambered to take the 7.62×51 mm NATO round, and featuring other improvements. The weapon is primarily found as the co-axial or commander's machine gun on post-war German tanks. Being only a 7.62 mm machine gun it is largely ineffective against all but the most weakly armoured, or open cabin, vehicles.

The Ho-103 is the variant of the Type 1 machine gun intended for fixed mounting. It is directly related to the Ho-104; the Ho-104 being intended for flexible mounting.
+
Being a derivative of the [[MG 42 (7.92 mm)|MG 42]] the MG 3A1 performs almost identically to it.
−
 
 
−
The action of the Ho-103 was developed from the American M1919/M1921 Browning. It was badly suited for use in a synchronized mounting, reducing the fire rate from 900 to 400 RPM. The Type 1 machine gun (Ho-103/Ho-104) is distinct from the identically named Type 1 machine gun derived from the German MG 15.

The Ho-103 is one of the weakest aircraft HMGs in War Thunder.
+
The MG 3A1 performs almost identically to the [[MG 42 (7.92 mm)|MG 42]], but has a significantly higher belt capacity at 1,000 rounds instead of 150. Like the MG 42, the MG 3A1 has an extremely fast rate of fire compared to other machine guns at 1,200 rounds per minute.

−
Projectile mass (and thus explosive/incendiary payload) is lower than both the American .50 BMG and the German 13x64B cartridges. Muzzle velocity is slightly higher than the German MG 131, but over 100 m/s lower than the American M2. The low mass and low velocity reduce the effective range of the weapon and increase the necessary angle for bullet drop compensation.
 
−
 
 
−
The Ho-103 is nose-mounted and synchronized in many Japanese aircraft, cutting the fire rate in half. The result is a machine gun that fires a weak cartridge with high drop and a short effective range at as little as half the fire rate of its contemporaries.

Description

The MG 3A1 is a German 7.62 mm General-Purpose Machine Gun (GPMG). The MG 3A1 is a post-war derivative of the MG 42 (7.92 mm) machine gun, re-chambered to take the 7.62×51 mm NATO round, and featuring other improvements. The weapon is primarily found as the co-axial or commander's machine gun on post-war German tanks. Being only a 7.62 mm machine gun it is largely ineffective against all but the most weakly armoured, or open cabin, vehicles.

General info

Comparison with analogues

The MG 3A1 performs almost identically to the MG 42, but has a significantly higher belt capacity at 1,000 rounds instead of 150. Like the MG 42, the MG 3A1 has an extremely fast rate of fire compared to other machine guns at 1,200 rounds per minute.

Usage in battles

Due to the very low penetration this weapon it is largely ineffective against enemy armour (although you may be able to penetrate some vehicles with extremely thin armour). The gun is primarily useful for incapacitating exposed crew members in open topped vehicles (although there are few such vehicles at the battle ratings this gun is found at). The gun can also be used for ranging on some vehicles, as well as marking enemy vehicles and obscuring the view of enemy players (shooting at their gun sight). You can use the gun against aircraft however it does minimal damage, and being co-axially mounted on most tanks can often not be brought / kept on target against aircraft. Clearing trees and bushes is another use.

Pros and cons

Pros:

  • Extremely high rate of fire
  • Very good belt capacity, especially compared to the earlier MG 42

Cons:

  • Low penetration makes it ineffective against armour
  • Low damage

History

The MG 3A1 is a German General-Purpose Machine Gun (GPMG) chambering the 7.62×51 mm NATO round, the weapon is derived from the war-time MG 42 and bears close resemblance to its predecessor. After WW2 Germany was looking for a new machine gun to equip the Bundeswehr (the German Army) and Rheinmetall was contracted to produce a new version of the highly successful MG42, from the Second World War. The original design plans for the MG42 were captured by the Soviets in the aftermath of WW2, and so Rheinmetall had to reverse engineer existing MG42s in order to re-create the design.

The new Weapon entered service in 1958 as the MG 1, a reverse engineered MG42, re-chambered for the NATO standard 7.62×51 mm, and with other minor differences. While MG1s were being produced existing stocks of MG42s were re-chambered from the 7.92 × 57 mm Mauser round to NATO ammunition and designated MG 2. Throughout it's service the MG1 was upgraded with MG 1A1, A2, and A3 variants being produced. In 1968 the MG 3 entered service as an improved version of the MG 1A3. The MG 3A1 is a variant of the MG 3 modified for use on armoured vehicles. The MG 3 family of weapons is still in service with the Bundeswehr and several other armed forces to this day.

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
