this may seem like a stupid question, but i'm kinda new to wharhammer 40k so don't get too annoyed. in the rule book it says a unit (unless its fearless) falling back and is under 50% of its starting number, it can't regroup. does this mean once a unit of, say, imperial guardsmen is falling back and is under 50%, it is completly useless for the rest of the game or until it reaches the table edge?



. Its an important tactic to utilize.
