Maybe using snipers and small teams of elite soldiers would be just as effective? That way, you can also find such nice things at their camps as papers and reciepts(Maybe not reciepts) proving that they've been funded by some country or another, if they were funded by a country of course, but if such things ARE at their camps, then they would be hard to find after the camp has just been incinerated by 100 gallons of Napalm or 10 cruise missiles.
