Had some disagreements on this card in a skirmish match. Say this card is played on an activation of Jet Troopers.

1.) Do both Jet Troopers perform Overrun or can only one trooper in the deployment perform Overrun?

2.) If both troopers can Overrun, does the "limit once per hostile figure" apply to both troopers or only one?

My interpretation was both Jets could perform Overrun because they are both part of the same activation. However, the once per hostile figure applies to the whole activation, so both troopers can't Overrun the same target for 4 damage. My opponent said only one trooper can Overrun.

I know this card is very popular with Jets, but I play in a primarily Rebel skirmish scene so I want to know for future matches.

There are two activations, the group activation and each figure's activation within the group (see Jyn's hair trigger for an example of an ability that triggers on the latter).

In this case, the card is played by a jet trooper figure and "your" activation refers to the activation of the figure you play the card on. So the card only applies to one trooper.

Sounds good! Thanks, Manatee.

Activation refers to figure activation unless explicitly said otherwise (except in a few cases).

Which makes it certain in this case is the rule that Command Cards with a restriction box must be played on a single friendly figure who matches all of the restrictions.

(In addition to "you" only referring to a figure or a player.)
