I can't say about the system in question, but having been around some of the smaller systems in the military, part of what makes them so good is often ease of operation. On shorter range fire and forget type systems it really doesn't take much work on the user end. You acquire a target and let it go. I would imagine it's similar on long range systems, as the missile must really do the homing and tracking work mostly in flight.

The majority of military hardware is designed to be user friendly. They know people are dealing with fatigue, stress, crap weather, etc often during use, and have to consider all those factors when they design things.
