T-55/M18

     Notes: This is a T-55 chassis with the turret replaced by that of the M18 Hellcat tank destroyer.  This modification is seen with some regularity inside the borders of the former Yugoslavia, but rarely outside that area.  The reason why this modification was done in the first place is not clear (the first ones were done in the early 1980s), but reasons from combining T-55s with non-functioning turrets and M18s with non-functioning hulls to the production of a cheap infantry support vehicle have been proposed.  About the only modifications that have been done to the turret were slightly better stabilization, night sights, and modifications needed to mate it to the T-55 chassis.
