Soltam M-68 of 155 mm was developed at the end the Sixties without no order specifying was placed for a model of cetype. The first prototype was born in 1968, and the chains of production started to turn in 1970. The only users known at the present time are the marine fusiliers of Singapapour and of Thailand, whereas the howitzer Soltam L-33 motorized, which borrows from M-68 its mouth from fire and its device of pointing, was adopted parl' armed with Tel-Aviv right in time to take share with the war of Yom Kippur War (1973). The tube of M-68 is 5,18 m long. It has of a brake of mouth with simple deflector, of a crest gate of smoke and a cylinder head with horizontal corner. The sytème anti-retreat is placed above the flanked barrel of two pneumatic cylinder jacks. In displacement, the mouth with fire is pointed backwards and is verroouillée on the mounting which is of the double trail type opening out of V. The wheels of road with tires are assembled on bogies and are equipped each one with an assisted brake, which allows speeds of towing of about 100 km/h. In position of shooting, prolongs it is supported by a screw jack. Four shovels of anchoring are envisaged: with each end from the fléches, and two in reserve which make it possible to point with the part in another direction without unearthing the first. 

M-68 fires the ammunition standard HE from NATO weighing 43,700 kg and a range from 21 000 m, lighting and smoke-producing shells, as of the specific projectiles Soltam which have more raised initial speed (820 m/s against 725 m/s) and an increased range (23 500 m). Soltam M-68 is not at the present time manufactured any more; the chains were converted with the production of the howitzer M-71, last-born child of the parts of 155 mm Soltam. It pourrat however to be produced again very quickly if important orders had placed. M-71 borrowed from M-68 its mounting, its cylinder head and its device antirecul, but it has a longer tube.
