In the codex the bio-electric pulse is triggerd during movement.
Is this at the beginning, at the end. Is there a choice. Do they have to move.
Can they use it after deep striking?
The thing about it triggering during movement is just a piece of fluff, it's most likely fired just like any other weapon, in the shooting phase. If it was actually used in the movement phase it would be explained a lot more clearly than it is now.
"I have seen you humans, trying to forge an Empire in the name of a corpse"
It's a shooting weapon. Fluff is just that, fluff.
The fluff doesn't even say it triggers during movement. It CHARGES during movement. Big difference.
Basically it's just a normal shooting weapon as far as the rules are concerned.
