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 38 kg (84 lb) HE bomb out to a maximum range of 9,600 m (10,500 yd) 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.
