This is a ZSU-23-4M "Beryoza" (1973) a lightly armored, self-propelled, radar guided anti-aircraft weapon system (SPAAG)of the Iraq army. It was my second attempt to assemble track link by link. It did take a while, but I like the result.
Earlier versions of the ZSU-23-4 were known as "Shilka"; starting with the "M" variant, they were known as "Beryoza."
