Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Pros:

• Insane rate of fire at 800 RPM to 950 RPM makes the Ho-5 the fastest-firing WWII cannon in the game
• Excellent accuracy while in prolonged bursts once gun is upgraded
• High explosive (HE) shells have Incendiary (I) element which work better than the Type 99's

Cons:

• Not the best explosive effect compared to other nations
• Low ammo pool and high fire rate require for trigger discipline
• Armour-piercing (AP-T) is bad against planes and armour > 10 mm
• Tracer belt is full of AP-T
• Mediocre muzzle velocity

History

Like the other nations that participated in World War II, Japan initially armed their planes with magazine-fed autocannons. However, the limited ammunition supply of magazine-fed cannons was identified as a limiting factor in their effectiveness and so Japan followed the lead of other nations and transitioned to belt-fed cannons during the war. For the Imperial Japanese Army Air Service, the belt-fed cannon of choice was the Ho-5, a scaled-up 20 mm version of the Ho-103 machine gun which was itself a copy of the American M2 Browning machine gun. The Ho-5 saw use on late war Japanese fighters in both the wings and engine cowlings and was retrofitted to be used in the flexible mounts of Japanese bombers.
