The M-68 was a 155 mm L33 caliber towed gun howitzer manufactured by Soltam Systems of Israel, and used by the Israeli Defense Force.

The M-68 is based on the Finnish designed 122 K 60 and 155 K 68 cannon series, first developed in the mid-1960s by the company Tampella Oy.

[3] The first prototype was completed in 1968 for trials and evaluations by the Israeli Defense Force (IDF), who were satisfied with the performance of the howitzer.

In the mid-1970s, the Israeli Defense Forces engineered an improvised self-propelled gun known as the Ro'em / L-33 to complement the towed M-68.

It mated an M-68 to a large, enclosed, turret atop the chassis and drive train of an M4 Sherman tank.
