I think Golly just got damn close, correctly identifying the gun being used right down to the "M" variant, but he'd have been even closer if he said it was the Sosna AD artillery system, developed by Nudelman Precise Engineering Design Bureau, CIS.
The missile tubes in the pic are probably Sosna-R although various IR missiles such as Igla, Mistral and Stinger are advertised as compatible.
OK. The system is Klinok-2, it has el-op FCS different from original Sosna and guns are 2A38M. Planeman was first to say Sosna, it's reasonably close.
Planeman - next, please.
