As built, the M-68 featured many tried-and-true qualities seen in other 155mm systems of the period. A four-wheeled, heavy-duty "split-trail" carriage (making up the tow arms) was used for supporting and transporting the 20,900lb weapon whose barrel measured 16.8 feet in length. Projectiles were fed by way of a horizontal breech block. The mounting hardware allowed the gun tube to be traversed between +/- 20 degrees from centerline and -5 to +75 degrees in elevation, giving the weapon a reach out to 13 miles using conventional projectiles (non-rocket-assisted). A typical operational crew numbered eight personnel.
The M-68 howtizer was also featured in the Ro'em Self-Propelled Gun (SPG) when mated to the chassis of the classic American M4 Sherman Medium Tank and set within a new fixed, boxy hull superstructure. This line of vehicle has since been retired from Israeli Army service.
The Soltam M-71 (detailed elsewhere on this site) is a variant of the M-68 design and features an air-driven loading hammer as well as a slightly longer gun tube.
