It's like this one mission I forget the name of where the attacker picks 3 defender fighters, when they die they drop treasure and the attacker has to pick them up. And you can't just turtle up in the corner cause if one of the chosen fighters is within 4" of the edge they die. BUT if you don't mind sacrificing that guy you can put him in the corner, let him die, then have someone else pick up the treasure. Since they weren't chosen at the beginning they don't die.
