The Marine Corps wants to use the ground-launched cruise missiles primarily as long-range anti-ship weapons.

One possibility for the Marines could be adapting its M142 High Mobility Artillery Rocket System (HIMARS) launchers in some way to fire MST missiles. However, the two weapons that HIMARS is presently capable of firing, 227mm artillery rockets and Army Tactical Missile System (ATACMS) quasi-ballistic missiles, are both substantially shorter than Tomahawk.
Separately in his testimony before Congress, Commandant Berger said that the Marines planned to integrate a ground-launched version of the smaller, shorter-range Naval Strike Missile (NSM) anti-ship cruise missile onto a derivative of HIMARS called the Remotely Operated Ground Unit Expeditionary-Fires (ROGUE-F). The present concept for ROGUE-F consists of a HIMARS launcher mounted on an unmanned chassis derived from the 4x4 Joint Light Tactical Vehicle (JLTV) tactical truck.
