I don't usually run three character squads, preferring for ships to give and absorb damage. That said, I'm thinking of doing this...

Nera

FCS, Ion Torpedo x2, Deadeye, E/2 with Recon Specialist

Wedge

Marksmanship

Biggs

Have Biggs trail after Nera taking hits while she blasts and ions depending on the target, while Wedge flanks. I'll likely get hammered with this, but I've been running undefeated for a couple weeks now and want the challenge.

A challenge would be 5 HWKs with blaster

but i like your list the only thing i would change is put Predator on Wedge or Swam Tactics then put R4-D6 on Biggs
