The other side to the player advice last strip:
If you're writing or running an adventure, try including a room with a rack of uniforms, be they military, security, or demon-cult acolyte robes. And if the players get the clever idea to wear them as a disguise, have them not quite fit. Thus making it bleedingly obvious to anyone who expects to see uniformed personnel walking around that these are imposters.
[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.]
Remember, "shorter" is a disadvantage in most systems, and gives you bonus points. Hence, R2-D2 was short. Chirrut isn't; I bet whatever Pete plays in Episode VII is.
Sally's disguise is perfect.
With Baze not fitting, Chirrut is basically unable to do anything. Unless of course, Baze operates a bunch of telescopes, binoculars, computer sensors, and overhead targeting drones to pass information to Chirrut.
That's a level of technology we haven't seen in this universe. I guess it's an upgrade from safety rails.
But... then he'd be a little short for a stormtrooper.
Perhaps Baze could dress up as a Wookiee-gram? I think he's about the right size for that.
Cassian: I'll take the officer's uniform. Bria, you take the landing marshal's.
K-2SO: I'll dress up as an Imperial droid.
Cassian: In that case, Bodhi, you can stay with the ship. Keep the engines warm; we might need to get off in a hurry.
Chirrut: Baze and I will wear the trooper armour.
GM: Baze won't fit.
Chirrut: What? Why?
GM: You maxed his Strength and Constitution. And made him tall enough to shoot over your head.
Chirrut: I knew I should have made myself shorter.
