| Notes | The type 97 was standard infantry mortar and like all medium mortars were mainly issued to independent battalions, although some were issued to gun companies instead of 70mm infantry guns. Like all mortars of this calibre, its origins lay with the Stokes/Brandt design and was widely used on all fronts. |
