We joke about it a lot, but the truth is that the military elites are quite sane and highly disciplined. They operate in small groups so they are highly dependent on each other. They won't accept some wild card in their group because he could get them all killed.

Now, they are quite innovative in their choice of equipment and tactics. That's what makes them so effective, as witnessed by how quickly a tiny number of special ops troops (mostly Army Green Berets accompanied by Air Force Combat Controllers with great air support) were able to work with the Northern Aliance to win control of Afghanistan. They accomplished in a matter of weeks what the Red Army wasn't able to do in years.

They're the best people in the world if you need them to come to your aid and your worst nightmare if they're coming after you.
