If you're giving the heroes access to a group of allies, it's a good idea to make them more than a bunch of faceless goons with identical stats and personalities. It may take some book-keeping, but try to produce a simple table showing each NPC's name, together with a stat or ability that they excel in, one in which they are below average, a single personality trait, and a goal (i.e. why are they here helping you?).
John, the goon with excellent marksmanship, but illiteracy, who likes cracking bad jokes, and is here out of a sense of duty is very different from Trevor, the goon with high strength, inability to be stealthy, who likes caring for animals, and is in the squad because he needs a good reference to find a better job.
[Reminder: Our guest commentators have not seen Rogue One. Part of the fun is seeing how their untainted impressions re-interpret the movie through the lens of our comic.]
In the past, we've seen the idea of "stealth until you fail".
But if you have a big huge squad, stealth isn't on the table. You know you're going to trigger all of the alarms. You know you're going to be detected. You're just going to go in blazing with all the guns you can muster.
After all, as long as experience points are awarded for killing enemies, being stealthy and avoiding combat just cost you experience points. (Maybe that's why experience points scale more by treasure gained, then monsters killed, in most versions of D&D. Thieves steal, clerics get donations, fighters loot bodies.)
And once again, Sally shows how much she is willing to "embrace the combat side".
Wow, 20 goons is quite a lot. Cassian's Charisma must be almost as high as Kyle's. Assuming of course that this is the sort of system that limits the number of minions/followers you can have based on your Charisma score. If it's not, then Cassian just told a bunch of Rebels that they have an opportunity to shoot Imperial soldiers with cool new weapons. Which frankly would have a very low Charisma check.
Either way, the shot of him and his mini-army behind him is pretty cool. If I were Annie I would have more fully elaborated on my epic entrance, possibly with musical accompaniment.
Bria: I go find Chirrut and Baze.
Chirrut: We're hanging out. In a hangar.
Bria: Where's Cassian?
Chirrut: I sent him off to recruit some minions to use the weapons. He has the highest Charisma.
Cassian: I'm back! I found this squad of 20 goons.
Bria: There's too many of them!
Cassian: Some of them came with their own weapons, so I had to recruit more.
Bria: Where's K?
K-2SO: I'm back here. Making sure none of them run away with my weapons.
Jav Mefran: Why would we run away? We're Rebels and we love shooting Imperials!
K-2SO: Oh! We're going to get along juuuust fine.
