Locking Zones of Control: Do you use them?

[Liebchen]

A company can't control a 3km wide and deep frontage, a battalion also wouldn't be able to put up more than a screening force. They would, however, prevent an enemy force from simply storming through. Likewise, a single division stopping an entire enemy corps from moving out of a pocket is also not entirely historically accurate (although it would depend on the morale and resolve of the defenders) which is why I prefer some sort of movement point multiplier, but I like the "middleground" ZOC multiplier 0 Operational Campaigns system as well.

Don't forget, they're not "stopping" anyone, they're just impeding progress for a couple of hours.

A company holding three klicks by itself implies that the next unit in line is three klicks away, i.e. there are two unoccupied hexes between them. This formation and disposition will not hold off a regiment very long at all, and will likely allow a breach in the line during the course of a turn.
