There was a pretty good one in an AFMBE game not too long ago. The PCs were in a small town when zombies attacked overrunning the town. The military had surrounded the town and was trying to contain the infection. They managed to get a humvee K9 unit from the police station and tried to get out of town. They found a field with no guards, but there was air support. A blackhawk helicopter was on them.
The minigun disabled their vehicle, but they did manage to get into the cover of the woods. The soldiers came down the rapel lines - the survivalist PC managed to snipe two of them as they were coming down the lines, but two made it in.
After a brief firefight, the PCs were wounded but victorious...except there was a helicopter, likely to call back for backup any minute. They quickly threw on the enemy uniforms and got on the radio - they said 'targets neutralized - we have wounded'. The copter descended.
At this point, I was preparing in my mind to screw the PCs over when they tried to BS their way onto the chopper. They had no knowledge of military protocol or behaviour. When they got close to the helicopter, the survivalist looked as the other PC and said 'Run.'
Then he looked at me and says "I toss a grenade in the door and run"
