Well, the Mark only applies until the end of the next turn or six seconds so it has to be reapplied, right? Also, most every army/police in the world uses suppression fire at range so its equivalent should work in the game. It's not so much physical control of the fight as it is the threat of potential attack that, if applied correctly, can make other combatants doubt and hesitate.
BTW, what happens if two fighters "mark" the same target? Do the penalties stack?
Forgot that part. Another fighters Mark removes and replaces any existing Mark.
