130 mm towed field gun M1954 (M-46)
In contrast, most Western field guns of this period had a dual high and low angle fire ability, a gun-howitzer.The barrel is mounted on a split-trail carriage, with deep box section trails and foam filled road wheels on the ground when firing and 50° of top traverse.It was replaced in Soviet/Russian inventory by the 2A36 Giatsint-B and the self-propelled 2S5 Giatsint-S. Several companies, like Soltam and RDM Technology BV, have presented upgrade packages for the gun.[9] From the mid to late 1970s Angolan M-46s were deployed with some success in the counter-battery role against South African artillery units, which possessed comparatively short-ranged BL 5.5-inch medium guns.[10] South Africa later acquired six M-46s from Israel for evaluation purposes; this likely influenced its development of the G5 howitzer, which was adopted to counter the range and effectiveness of the FAPLA field guns.[12] Cuban and FAPLA M-46s were used most notably during the Battle of Cuito Cuanavale, where individual guns were deployed in ones or twos rather than concentrated in single positions to reduce the threat posed by counter-battery fire from South African G5s.[13] Cuban tacticians were able to repeatedly stall a South African mechanized and armored offensive by using minefields to channel the attackers into bottlenecks where the M-46s could concentrate their fire.[14] A version of this gun, possibly the Chinese-manufactured Type 59–1, is suspected to have been used by North Korea for shelling the South Korean island of Yeonpyeong in the Yellow Sea on 23 November 2010.[16] According to Ukrainian press reports, Russia has increasingly sourced the guns' 130mm shells from North Korea as its domestic stockpiles of this ammunition type have been depleted by the war.
