FOR THIS POLL, PLEASE ANSWER HOW YOU CHOOSE TO PLAY THE GAME, NOT NECESSARILY WHAT THE RULES AS WRITTEN (RAW) SAY.
The 'Pile In' Moves rule on page 44 of the rulebook says: "At the end of each Assault phase, models in units that were locked, but which are not themselves engaged in combat MUST move up to 6 [inches] in an attempt to contact enemy that were in the same combat."
The Assault Phase Summary on page 36 of the rulebook says:
"RESOLVE COMBATS 1. Pick a combat. [Steps 2-5] 6. Pile In. If units are still locked in close combat then any models not in base-to-base contact are moved 6 [inches] towards the enemy to continue the fight next turn. 7. Repeat until all combats have been resolved."
QUESTION: When you play, at what point during the Assault phase do you make Pile In moves: at the end of each individual combat, or at the end of the Assault Phase? Also, if a victorious unit consolidates into a previously unlocked enemy unit[s] (creating a new Assault), do both sides immediately make a Pile In move?
OPTION A. I follow the rules text presented on page 44: All Pile In moves are performed at the end of the Assault Phase (after all combats have been fought and resolved). Also, if a victorious unit consolidates into a previously unlocked enemy unit[s] (creating a new Assault), both sides immediately make a Pile In move.
OPTION B. I follow the rules text presented on page 44: All Pile In moves are performed at the end of the Assault Phase (after all combats have been fought and resolved). However, if a victorious unit consolidates into a previously unlocked enemy unit[s] (creating a new Assault), neither side makes a Pile In move this Assault Phase.
OPTION C. I follow the Assault Phase Summary on page 36: Pile In moves are made at Step 6 of each individual close combat. Also, if a victorious unit consolidates into a previously unlocked enemy unit[s] (creating a new Assault), both sides immediately make a Pile In move.
OPTION D. I follow the Assault Phase Summary on page 36: Pile In moves are made at Step 6 of each individual close combat. However, if a victorious unit consolidates into a previously unlocked enemy unit[s] (creating a new Assault), neither side makes a Pile In move this Assault Phase.
OPTION E. Something else entirely: reply exactly what it is below.
