There is no debate that weaponized drones have forever changed the tactical-level conduct of war. Even nations without access to larger drones are showing just how dangerous cheap commercial quadcopters are on the battlefield. Just look at this video of a weaponized civilian drone HAMAS used to take out an Israeli remote control machine gun during their October attack. Or their use against comtmunications towers. Here is another video of a commercial drone being prepped for use in the ongoing Sudan civil war. You now have the power of surveillance and close air support organic at the squad level for a few thousand dollars instead of a few million.
