A couple days ago me and two of my friends were playing woodsball scenario at Big Foot paintball (north of Montreal), and the objective was that one of the teams had to bomb a fort (putting a bomb on the barrels inside the fort), while the other team had to defend it. The teams were of about 20 players on each side. Me and my friends were on defense. Right as the game starts, both my friends and in storm into the fort and head to the left side and try to protect the entrance. After a few seconds, we turn the corner leading into the last corridor leading to the entrance. Now, this is a CORRIDOR, no cover whatsoever, and my friends and I are perfectly aware of it, but it has to be defended. So we all three walk slowly side by side with our fingers on the trigger, markers pointed straight at the door, ready to shoot and the slightest movement, knowing we were going to have to shoot first in order to live should an enemy reach the door. About ten feet away from the entrance, an obvious first-timer comes in running through the door without taking a look first! Each of us instantly shot a volley of paintballs at him, nearly point blank, straight to the torso.
So yeah, after the game was done (we won), I went to apologize for this little incident.
