I've worked on the ground in Afghanistan on a Mechanized Infantry Platoon. There's nothing more calming than hearing the buzz from a drone keeping an eye on the terrain from above and reporting to the TACP while you're on the ground. We where saved multiple times from running into ambushes and IEDs thanks to drones. Sure, Apache's could do the job as-well, but when they run out of fuel, and they do more often than a drone, you're on your own.
Sure, that's another mission from flying a drone to a compound in Pakistan and dropping some explosive on it, that I can not comment on since I have not seen the Intel behind those missions.
