Hello

If rebels "win" an allie as rebel trooper, can they use the advanced red version, or must they only use the regular black version?

They must use the regular grey version to start.

Packaged with the Rebel Troopers ally pack comes a second mission to unluck the troopers for the campaign. If you unlock a second copy of a generic ally the campaign it then upgrades the units you may bring in to the Elite (red) version.

Page 5. RRG under Rebel Allies

If an ally has both a regular and elite Deployment card, only

the regular card can be used as an ally. If an ally is rewarded to

the heroes and the heroes have already earned that ally, they

can use either the elite or regular Deployment card.

Thanks a lot for your answer, very precise!
