I don't mean grouping as in two squads. I mean the proximity of one squad's members walking close to one another. If they are more spread out it wouldn't wipe squads so easily, like CoH 1. Very rarely did a mine wipe squads unless they were already badly damaged.
I know.
Squad members grouping up is predictable based on cover. Gotta be careful to not let that happen if you're worried about mines.
