Description: Whenever there are gaps in the formation of a unit, or incomplete ranks other than in the rear rank of a unit, the unit’s formation needs to be reformed into a viable formation. However, remember that Unit Boundaries and model placement in units are frozen during a Round of Combat. In this case, only follow the rules below when these are unfrozen, just before moving Broken and Pursuing units.
When redistributing models to fill gaps in the units formation, fill gaps and incomplete ranks with models in the following priority order:
• Move models from the rear rank,
• Move models from ranks other than the front rank,
• Move models from the front rank.
Avoid changing the number of files in the unit. If this is impossible, such as for a unit that only has a single rank unit, fill gaps by sliding all models from one side of the gap towards the other side.
Maintaining a Viable Formation in Combat
During a Round of Combat, the Unit Boundaries of involved units are frozen, and models are not moved around inside the units to maintain a viable formation; not even to fill empty gaps inside the unit formations. Apply this from the start of a Round of Combat, until just before Broken units perform their Flee Moves. See Combat Phase chapter for further details.
Remember that when calculating the number of ranks or files a unit has, gaps are considered filled by models in back ranks as normal, potentially reducing the number of ranks or files.
