My favorite comes from a game we just played last week or so. The property we play at has a small railroad track (not real, think an amusement park sized train) and we were playing a linear game with each team of 9 trying to take the other team's flag at their end of the 200 yard or so stretch of straight track. There's very heavy woods lining each side of the track. Obviously, there was a lot of fighting going on on the track itself, so I flanked right, as wide as I could and moved forward. As I thought, the opfor that were trying to flank us on the track had moved toward us, to their left (same side of the track as me) but were closer to the track than I was. I slowly crept forward, and as each burst of fire erupted from the track, I popped off a few shots. I eliminated 7 players, all from the back and/or side before they re-entered the game and knew where I was already.
