1/100 SU-155 Artillery Tank

Following the success of the JN-1 and JN-2 on Rossbera, the chuyinka developed their own version of an armoured, self-propelled 155mm howitzer.  The SU-155 can operate at greater ranges than either of the vehicles that inspired it, with a longer barrel and maximum elevation of 44 degrees.  The main gun is offset to make room for a ball-mounted machine gun in the front of the turret, to mow down any troops that manage to get close enough to the line of tanks as they are bombarding targets at long ranges.  The SU-155 can also be used at shorter ranges against trenches and bunkers, as it is built on the TVS chassis, but it is not intended for that role.  Given how well it performed, however, the SU-155 is effectively the first true chuyinka assault gun, and only slightly different from the all-purpose heavy AFV designated ShU-1.
