The Type 92 battalion gun (九二式歩兵砲, Kyūni-shiki Hoheihō) was a 70mm (2.75 in) light

infantry battalion
included two Type 92 guns; therefore, the Type 92 was referred to as "battalion artillery" (大隊砲, Daitaihō).

History and development

The Type 92 battalion gun was designed in response to issues with the

infantry divisions did not like the fact that they had to carry two different types of weapons with different ammunition into combat. As a result, the army technical bureau developed a design which could be used either at low angle direct fire to take out fortified positions, machine gun nests and light armor, but also could be used at high angle indirect support fire. The caliber of the new weapon was increased to 70 mm to address the issue of inadequate firepower. The new design was available to front line divisions by 1932.[3]

Design

Somewhat unusual in appearance, the Type 92 battalion gun had a short gun barrel with a split trail carriage. The barrel could be configured from a horizontal to near vertical position with a hand-crank. It had an interrupted thread type, drop breechblock mechanism. Lightweight and maneuverable, it was designed to be pulled by a single horse, although in practice teams of three horses were usually assigned. Its relativity small size and weight also allowed it to be manhandled by its crew for short distances. The wheels were originally wooden, but were changed to steel after troops complained that the noise from the squeaky wooden wheels was a threat.[4]

Combat record

The Type 92 battalion gun was first used in combat during the

Battle of Nomonhan[citation needed] and subsequent Second Sino-Japanese War.[5] It later accompanied units assigned to the Pacific front and was used with considerable effectiveness against Allied forces throughout the South Seas Mandate and in Southeast Asia
.

During the

People's Liberation Armed Forces of South Vietnam during the Vietnam War.[7]

Surviving examples

Type 92 gun at Dharma Wiratama Museum in Yogyakarta, Indonesia

Two guns are preserved and on display in a small park on Main Street in Lakeport, California. One gun (on the southern side), with serial number 399, has unperforated sheet-metal wheels, while the wheels of the other gun (to the north) appear to have been restored with new material.[10]

Two guns are at the Marine Recruiting Depot Museum in San Diego, California, put on display outdoors.[citation needed]

Another is on display in front of VFW Post 7589 in Manassas, VA.[citation needed]

One gun is on display at the Redcliffe branch of the RSL in Queensland, Australia, reliably reported as coming from WWII operations on the

Kokoda Trail against the Japanese in Papua New Guinea. One other example is located at Army Museum Bandiana
, Victoria as part of their artillery display.

A Type 92, without its shield, is displayed at the U.S. Army Field Artillery Museum at Fort Sill, Oklahoma. Its picture is attached here.

One Type 92, painted green, was formerly on display at

Japanese invasion of the island
in 1942. Following a recent renovation, the gun was removed and its current location is unknown.

A Type 92 gun is on display at the lobby entrance of Dharma Wiratama Museum, an Indonesian Army museum at Yogyakarta, Indonesia. The museum plaque mentioned that the gun was used during the Battle of Ambarawa in December 1945.[11]
