The Proximity rules says that once a unit gets within 12" of the enemy all of its movement must be within its front or rear quarters.
1. Is there any other restriction to this movement? I.e. does the unit have to move straight without chaning facing or can it move sideways, forward first and then sidewasy, etc. as long as it stays completely within its front or rear quarter?
2. Does the entire unit have to stay within its front or rear quarter or only the front of the units? For example, is it ok if the units rear extends out into a side quarter?
Thanks.
