tactics: primary target
Tactical behavior in the movies drives me nuts.
Scenario 1: a bad guy is holding your wife hostage, with one arm around her throat and a gun to her head. You're fifteen feet away, pumped with adrenaline, and have about a 2" wide target window to the BG's head. He tells you to put down your gun. Of course, he'll then kill you both. In the movies, they *always* put down the gun, and wait for a plot complication to rescue them.
TAKE THE SHOT! You might miss and kill your wife. Or the BG's trigger finger might spasm when he dies and kill her. The point is, she's going to die anyway. You're trading certain death for both for maybe-death for one. My wife understands this; every time she sees the situation in a movie, she's bouncing in her seat and shouting "SHOOT! SHOOT! YOU STUPID #*@&*@$!"
Scenario 2: you have the BG covered. The situation is very tense. Then, from behind you, one of the BG's cohorts tells you to drop the gun. Or you hear a sudden noise. Or something else happens.
If the situation turns to shit, don't turn around to look. TAKE OUT THE PRIMARY TARGET! It only takes a fraction of a second to pull the trigger. *THEN* turn around and find out what's going on. Your number might be up, but at least you accomplished the main job. You should hear my wife shouting "TAKE OUT THE PRIMARY TARGET!" I think she got that from me...
I think I read way too many Donald Hamilton books when I was a kid, and some of the preaching stuck...
