The M-66 is a 160 mm mortar manufactured by Soltam of Israel. The weapon was based on an earlier 160 mm design, the M-58 mortar by Vammas of Finland. It can fire a HE bomb out to a maximum range of and requires a crew of 6-8 to operate.
In addition to the towed variant, the M-66 was mounted on a Sherman tank chassis, modified with an open-topped compartment with folding front plate, resulting in the Makmat 160 mm which was adopted in 1968.
