Curiously designated as the Type 97 'high angle infantry gun', this Japanese mortar was introduced into service during 1937 alongside the 90 mm 'heavy close attack gun' (also a mortar), both of which shared a common form of collimator sight. Although heavy to carry, the mortar represented the most effective form of mobile fire support available to either side in the Burma campaign.

Hi. Well, there were three different caliber mortars designated "Type 97" Type 97 8 cm High-angle Infantry Gun Type 97 9 cm Mortar Type 97 15 cm Mortar In addition there was a Type 97 experimental Short Mortar, too. Note: Mortars used by infantry units were designated "high-angle infantry gun". "Mortars" were used by special trench mortar units only. Yours tom!
