If you don't mind me asking I would like to know how you found this? Sounds like something I might need to know how to do someday.
My sources are independently verified and not available to be interviewed --- just kidding. Found it with a google search. Others have since posted that the 34567 PO shows up on some other legitimate Guard documents but on them it is attributed to a different unit. It would not be uncommon for units to share a box but is also not uncommon for a Rat forger not to do his homework (like learning to abreviate your own rank correctly after 20 years of service.)
