Col. Brown's autobiography
Dancing with Devils. I got a copy from him and finished it on the plane (7 hours in the air, I read fast). This fellow did more in a good month than I've done in my life. Got into and thrown out of Special Forces twice, stripped of a security clearance for associating with anti-Castro rebels but still got into Command and General Staff College (where top secret clearance is considered a requirement for entry ... knowing an experienced noncom with connections who'd do lots for friendship and a bottle of fine bourbon helps) entered Afghanistan while it was under Soviet rule, had a South American dictator put a contract on his life, ran humanitarian supplies into Bosnia, etc., etc..
I was esp. amused by one sniper's trick. In guerilla war, he found the problem was figuring out who was the leader and worth a shot. So he'd leave envelopes on the trial with "Take me to your commander" written on them in the local language. When the point man took it to somebody, he knew his target. Later they figured this out and told the commanders, who forgot to tell their men. Then he waited for the point man to run back with the envelope and knew his target was the person who put his hands up in a "stop" gesture and started yelling at the point man.
