The VTM 120 also carries 70 rounds for the mortar and offers basic ballistic protection from small arms fire and shrapnel for the crew.

The RT-61 can also be towed by the AMX-10 TM (Tracteur de Mortier), which is a version of the AMX-10P tracked APC or the future French Scorpion SERVAL Vehicle.

Early on, the 120 RT weapon became tied to the development of the MV-22 Osprey, which would contain a Growler ITV jeep that would tow it; both efforts were troubled and experienced delays.

The extra range came from tail fins for stabilization and canards near the nose to make in-flight adjustments and make it glide as it descends, and the greater lethality was a result of this flight path; normal artillery rounds impact at a 45-degree angle, which blows the top half of the round straight up into the air, but descending at a sharp angle places more energy and fragmentation directly on a target.

Greater accuracy also reduces logistical burdens, as using fewer rounds to destroy one target means a unit can last longer without needing resupply.
