"National Defense Authorization Act for Fiscal Year 2001 (as enacted into law by Public Law 106-398; 114 Stat. 1654A-38) that, by 2015, one-third of operational ground combat vehicles be unmanned."

I'm guessing they won't all be logistical delivery vehicles.

I'm working a very fast cargo transport UAV for DoD that, after cargo delivery to the soldiers, has enough capacity to hold several people. It will have no pilot or joystick, rather flying blind like a cruise missile to its next waypoint.

Now tell me that if you are combat wounded or reacting to a poisonous snake bite, you'd rather wait for medical treatment via the next piloted lift dispatched once/or if it's safe enough for them? I predict MASH-style evacuations will happen sooner than later.
