Overview
The Type 92 battalion gun, commonly called Kyūni-shiki Hoheihō, was a light howitzer developed for the Imperial Japanese Army to provide direct and indirect fire support to infantry units. Its designation, Type 92, reflects the year of adoption (Imperial year 2592, corresponding to 1932). Because it was assigned to individual infantry units, soldiers often referred to it as "battalion artillery" (大隊砲, Daitaihō).
Design and characteristics
The weapon was designed to be compact and mobile so it could accompany foot soldiers and be moved over rough ground. It had a relatively short barrel and allowed high angles of elevation for lobbed fire, making it effective for engaging enemy positions behind cover. Typical ammunition included high-explosive and smoke rounds for suppression and signaling.
- Role: light howitzer for close infantry support (howitzer).
- Organization: issued to infantry sub-units and battalions within the Imperial Japanese Army.
- Operational context: served with infantry formations at the battalion level.
Service history
The Type 92 entered service in the early 1930s and was used extensively during the Second Sino-Japanese War and throughout the Pacific campaigns of the Second World War. Its distribution at the battalion level gave small infantry formations organic firepower, a practice that reflected interwar thinking about combined-arms infantry operations.
Tactical use and notable features
In the field the gun was employed for close support against enemy trenches, machine-gun nests, and fortified positions. Its compact size made it easier to conceal and emplace than larger divisional artillery, and crews could shift firing positions quickly. While not intended as an anti-armor weapon, it could be used in direct-fire roles in emergencies.
Legacy and distinctions
The Type 92 exemplifies prewar efforts to give infantry units independent fire capability. It contrasts with heavier divisional guns that remained at higher echelons and highlights the balance armies sought between mobility and firepower in the interwar and WWII periods.
