Tip: "A fight is one of the quickest ways to tell if someone isn't who they say they are. If you say you are Russian but fight like an American, consider your cover blown, which means you better know Sambo, the mixed martial art of Russia. Of course, you also have to win the fight; a great cover ID doesn't help much if you're dead." Tip: "One of the hardest things to do in a fight is to make it look like you're trying to kill someone without doing any permanent damage. They don't teach any half-moves in combat training. There are moves designed to kill and maim as efficiently as possible. If those are off limits, one option is open your fist right before a punch lands. Painful, but the force is distributed. Another showy option is a kick to the shoulder. You might break a rib or two; but if you aim right, nobody is going to the morgue." Tip: "There are some fights you just can't win. A force can be so overwhelming that no tactical approach in a fight is going to lead to a victory worth having. When you can't win in a fight, sometimes you have to settle for making sure that if you lose, everyone loses. It works for nuclear weapons; it works for me." Tip: "Spies make great neighbors; they're polite, they keep the lawn trim, and they never crank up the music at night. They don't stand out, because they don't want to be found. So if you're hunting for a covert operative and all you've got to go on are the names of a few dozen suspects, you're out of luck... unless you know where to look." Tip: "A criminal cover ID isn't just about a new name and phone number; it's about fitting into a culture with its own rules and hierarchies. It's a world where bank robbers are the rock stars, con artists are the snobs, car thieves are the blue-collar guys, and safecrackers are the artists." Tip: "When you're claiming to be someone you're not, the key is commitment. You've got to sell it like your life depends on it, because sometimes it does. One reason to work with the same people is you know each other's moves, so if you shoot at your team in the middle of an operation, they know to go with it." Tip: "Facts are the hallmark of a good false identity. It is harder to create history than it is to alter it. Plus, the more truth to your lie, the easier it is to remember."
