Chapter 29-1- Beyond Our Walls Part 1

[Cabbage Patch]

One question that I have is, what does Puck mean when he says that he is Prior Active when the Col. assigns him to Michael for training?

There's a long history of people in the active Army looking down on their National Guard and Army Reserve counterparts. There was a time when there might have been some justification to those views, but these days those elements have probably seen as much war-time service as the active duty Army. I think CPL Puck was just venting, something he's quite adept at. Notice how his attitude changed when he realized that Michael had combat experience in the Middle East.
