Hell fire is kind of heavy for most of these drones which are generally smaller than the Predator. A LMG might be possible, but you couldn't carry much ammo. However the drones would allow the operators to continue to track the illegals pending arrival of Blackhawks filled with Border Patrol agents on the scene, or whatever other "assets" they choose. Especially at night, but in the daytime too, the drones are pretty hard to spot from the gound with the naked eye, and they don't make all that much noise either.
Hehehe...
