Contents
Description
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.

Comparison with analogues
The Ho-103 is one of the weakest aircraft HMGs in War Thunder.
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.
Usage in battles
- Due to the low velocity, it is often impractical to use the Ho-103 at anything other than close range
- The typically low ammunition count of Japanese aircraft using the Ho-103 means that ammunition must be conserved judiciously.
- The Default and Tracer belts should not be used if possible. The lack of explosive incendiary bullets greatly reduces damage dealt.
Pros and cons
Pros:
- The weapon itself is fairly light
- The fired 12.7 mm rounds consistently do more damage than 7.7 mm
Cons:
- Low muzzle velocity
- The available shells have comparatively weak payloads
History
Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
