The Army is creating remote-control mortars

The Army wants its mortar systems to be even more mobile, accurate, and quick to fire. Moreover, they want mortar crews to be able to park a Humvee with a tube mounted to it and then get out of there.


The Advanced Direct Indirect Fire Mortar system gives them all of that and a direct-fire capability too.

The ADIMs is currently being tested and displayed as an 81mm system on a Humvee, but it could be adapted to other calibers and light tactical vehicles. A "soft-recoil" system allows larger mortars — historically limited to larger, heavy vehicles like the Stryker — to be mounted on the Humvee or its replacement, the Joint Light Tactical Vehicle.

Humvees are able to reach a lot of places Strykers and other larger vehicles can't, allowing the mortars to quickly reach parts of the battlefield they otherwise couldn't.

Once the mortar is in position, it can be manually worked by a standard mortar crew or remotely operated by a fire direction center. In theory, this would allow the weapon to be dropped or driven into position and then fired without a human mortar crew. Someone would still have to secure it though, since it's a powerful, advanced weapons system.

But then mortarmen could just emplace the weapon and play spades while the FDC worries about firing it. Once the weapon is fired, it's capable of being moved within 50 seconds to avoid enemy counter fire.

The weapon generated excitement during a display at Fort Benning in Jan. where it fired 174 rounds, rapidly changing targets and missions between shots. And, the direct fire capability of the mortar would allow it to fill a gap in the American mortar arsenal.

Of course, the ADIM only really matters if it makes it to the battlefield. The ADIM shares a lot of traits with the Marine Corps Dragon Fire and Dragon Fire II mortar systems.

The Dragon Fire was tested by the Marine Corps, upgraded to the Dragon Fire II, and then shelved. Instead, the Marine Corps adopted the M327, a highly-mobile, rifled mortar without the automation of the ADIM or Dragon Fire systems.
