if this is the siege i think it is, then i'd like to say that its very stupid when a line moves out in 3 (like your rules state). Then they get hit by a cannonball and only 1-2 remaining. Then they just continue charging the wall as they're normally close to it, but then they get called out by an admin for rambo even though they can't control whether they get hit by a cannonball or not.
You slayed me and my guys multiple times without realizing we had just been shot, or a cannonball hit us, we moved out in lines of 3.
And good luck doc
