Double Press X, whith or whithout Presing K, either you send all you squad or one soldier, the green order will be become Yellow, yes yellow means move to me at last, so the soldier will use ALL stamina and move it, no matter want, no matter want, so in a time of less that one second, it will be a sprint other. want make very good for gamers, and easy to code.
if it is getting bullets, he will run there.
spriting, is good to retreat from a artilhary area, go from one cover to other, regroup, and advance quicly in the start of the game.
cheers.
