The Soltam K6 is a 120 mm mortar that was developed by Soltam Systems of Israel. It is the long-range version of the Soltam K5 and has replaced older systems, such as the 107-millimetre (4.2 in) M30, in several armies, including the United States Army. It is much lighter than the M30, has a greater range, and can sustain a rate of fire of four rounds per minute, while the M30 could sustain only three.
