This, on the other hand, is fairly easy:

Italian Model 08/13 65mm L/17 mountain gun, original designation Cannone da montagna 65A, later designation Cannone da 65/17 Modello 1908/1913. Since 1930s tactical role was cannone d'accompagnamento, which means roughly the same as "infantry gun", although the 47mm Böhler partially replaced it in that role after 1935. Still available in large numbers and widely used in WW2 as an infantry gun (also for indirect fire when required) and emergency AT gun (HEAT was available since 1941). The Italian equivalent of the German 7.5 cm le.IG and the Soviet 75mm M27 regimental gun.
