ok i tried the demo,
i tried moving just as it said in the gif
the men bunched up fine
i ran across, and only one followed, he then got excited and ran right through the building and out the wall on the other side and got shot.
then the rest all ran across at once, 1 stopped in middle and got shot
the rest bunched around me and i couldnt see,
next thing i know one of my guys pulled out a nade and tried to throw it at who knows what, the grenade hit the wall next to me and the entire surviving squad was blown to pieces(including me).
i dont know what you were trying to do but, as the demo went
before the script if i tried to have them run across, 2 or 3 would die
with the script if i try to run across everybody died(me included).
maby work out some bugs in this.
