Alpha Strike Companion Errata p.16, in reference to the update to the Pursuit Lance Special bonus ability (ASC p.152):
The Pursuit Lance may choose an enemy Formation rather than a single unit as the target for the Blood Stalker SPA. If this option is used, all members of the Pursuit Lance must choose the same enemy Formation for the Blood Stalker SPA granted by this ability, and the destruction of the chosen Formation is the only time the Pursuit Lance may change the target of the Blood Stalker SPA, by choosing a new enemy Formation
Is "Destruction" implying that the formation has been neutralized (i.e. reduced below 50% and thus dissolving cohesion) OR is it wanting 100% removal of such forces?
What about crippled/disabled units that are in Forced Withdrawl?
I can see arguments for both cases, but I am asking for clarity before suggesting it to my players (The change to Bloodstalker found in the Errata on p.4 of the errata is sensible enough to encourage the individual, but I believe its different when having to eliminate an entire formation)
