Unclear if that means facial features, or just appearance.
"At least our voices are unique, I think to myself."
This is the chron Esna was thinking of, I believe. It mentions "stock clones", for budgetary reasons. It seems to be Republic, as a couple of the bods are/were Valklears.
These may however, be the prototype troopers, while the Republic gets things in order, and DUST troopers proper, may keep their own faces, and have variations in appearance, with non-stock clones, once the budget is no longer an issue.
Would think the psychology of seeing identical faces all the time would cause more problems than it solves logistics wise, no?
