Initially I wanted to highlight the 501st and Rex with ‘celebrated’ and ‘heroic’ to give a little context (since they’re not in the movies), but I agree they’re a little soft. Perhaps instead I’ll take the opportunity to make it clearer that they’re Anakin’s legion.
“As Anakin and his decorated 501st Legion widen the net, his trusted CAPTAIN REX inspects the Republic’s long-range listening stations.”
