The Marine haven’t waited for the Army or Air Force to take the lead on unmanned aerial drones or unmanned trucks when it comes to delivering cargo.

The Corps announced the completion of their first test of multiple unmanned trucks simulating a cargo convoy using Oshkosh trucks. The test took place at Fort Pickett, Va., from July 24 to Aug. 5. Marine Corps leaders said the next step is an operational test in Afghanistan.

Marines and Lockheed Martin contractors are already flying an unmanned cargo helicopter in Afghanistan where it has exceeded expectations. The K-MAX has flown over 4,500 pounds of cargo and at least 500 sorties since the Marines deployed the cargo helicopter in December 2011. Marine leaders recently chose to extend the K-MAX’s deployment for the third time out to March 2013.

Seven Marines spent three days training on the Oshkosh trucks outfitted with unmanned ground vehicle technology before the test. Oshkosh lauded the short training period as proof of the ease of use Marine Corps leaders are seeking.

Oshkosh’s unmanned ground kit can be installed into new and old vehicles, even models other than Oshkosh’s. Pentagon officials have not set a timeline for deployment of the unmanned trucks to Afghanistan.

Ground commanders have long sought the ability to send ground convoys without human crews as some of the highest casualty rates during the wars in Iraq and Afghanistan came from Army and Marine convoys getting hit by improvised explosive devices (IEDs). Soldiers and Marines have often questioned why the military couldn’t build unmanned trucks when it was flooding Iraq and Afghanistan with unmanned aerial vehicles.

Much like with the K-MAX, the Army has chosen to sit on the sidelines and wait to see what the Marines can produce with their unmanned trucks. Similarly, the Air Force has focused primarily on strike and intelligence, surveillance and surveillance drones rather than ones that can carry cargo.
