The most common team maneuvers I have seen at fighter practice are the V and the uber-wide flank. In another thread, I posted how to defeat an uber-wide flank before explaining a better way to flank because I believe that the best way to fix a bad habit is to teach everybody how to render it ineffective.
For those unfamiliar with the V, a more aggressive fighter approaches an opponent (or holds his ground when an opponent approaches him) and the guys on either side of those two individuals fall back 2-3 steps with the intention of running forward again after combat is initiated. I have seen V's 4 man deep.
I believe Daggenoth is the best person at our local fighter practice to walk a V (much better than I). I believe doing it is largely a matter of timing, battlefield awareness and aggression.
When two V's meet each other, the point man needs to be aware of how much time it takes the newbies behind the other point man to reach him and aggressively attack the other point for only that long. If he can defeat his lone opponent that quickly, great. If he cannot, he needs to take a long sidestep along with an attack as soon as the man on that side gets withing range and then another step (with an attack) to place the newbie between himself and the other point man. Usually by this point the other point man is engaging the two other newbies that were behind you and you have a second or two to kill this opponent before the next newbie in the V reaches you.
This process is repeated until somebody stops rushing at you alone and you can run back to the swirling melee formed out of the other side of the V.
I've seen Dag kill as many as 4 people on my side in under 10 seconds when a V formed behind me, engaging each of them in single combat for a second or two before moving on to the next person conveniently lined up like dominos.
