Dragon mke two versions of the ZSU-23-4, the original ZSU-24-v1 and the later ZSU-23-4m. The later version had improved cannons which extended barrel life (among other improvements).

Which ZSU version is the RB models 35b29 cannon barrels correct for? Also, was the ZSU-24-4M used during the Yom Kippur War?

Regards,
Rob

Each of the two, although the gun is (AZP-23), but the 4M variant increased the diameters of the liquid cooling tubes in order to continue firing him.
The Yom Kippur war, the V1 version was the color of Egypt.
