Soltam K6

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.

The K6 entered service with the United States Army in 1991 as the M120 Mortar System. Its mission is to provide heavy weapon, high-angle organic indirect fire support to the unit commander. The M120 is used by both mechanized units and light infantry in certain situations. Another feature of the M120 is the M303 Sub-Caliber insert, which allows the mortar to fire 81 mm ammunition.

The M120 is transported on the M1100 Trailer by the M998 Humvee. The version that is mounted on the M1064 and M1129 mortar carriers is known as the M121.

In 2007, the U.S. Army ordered 588 M326 MSS (Mortar Stowage Systems) from BAE Systems. Here, the assembled mortar is mounted on a truck, Humvee or M1101 trailer and can be mounted and dismounted in less than 20 seconds.
