Hypothetical situation: Garm is on a team with General Wedge Antillies and a random follower with Double Attack, let's say Boba Fett, Mercenary. Would the Mobile Attack gained from Wedge work with Garm's CE? More specifically, would Fett be able to move 1, shoot twice, and move 2 more afterwards?

Yes. Greater Mobile Attack is the same as Mobile Attack. You just get to make all of your possible attacks with Greater. The movement is the exact same.

I wasn't asking about Greater Mobile Attack. Besides, the Fett I mentioned doesn't have it. I knew I should have used a different figure as an example.

I wanted to know if combining Mobile Attack with Garm's CE would let a figure mobile with the lowered speed while still getting the extra attacks. Getting a sort of lesser version of Greater Mobile.

Garm's Commander Effect
Each follower can move up to half its Speed and still use Force powers and special abilities that grant extra attacks.

Ah. Thanks. That's what I get for not looking at the FAQ before posting.
