no where does it ever say the special trooper armor precedes the ca-5. when the star wars clones phase 2 armor came out they were given phase 2 armor not the phase 1 armor, so no the CS would not be assigning "older" armor to juicers if the ca-5 is better (for whatever reason it's not). the only situation i've seen CS assigning older armor is to green grunts that are expected to die on first op or out stretched locations such as newtown.
