In the event of an enemy with missile defense systems, border security and armed guards a UAV maybe the only choice. A UAV with real time video could be remotely controlled much like a model aircraft and fly into the target area. In the event the target was a small group of enemy leaders or the command and control center this tactic could work if you could get within 10-20 miles. No matter what modern day defenses the enemy has you can fly right past them unencumbered directly to the target.

A single mission UAV in the form of a large model aircraft could do the attack on the enemy relatively easy. Let us look at some of the inexpensive units available, which you can build in country. This might be the perfect tactic for our CIA, to take out the enemy commanders and generals. Model Airplane hobby folks have long known of the servos you can buy which allow a model aircraft to make a practice bomb run.
