If it has your name on it, then you need a copy. If it affects your health, paycheck, or other element of well-being, then you need two copies. The Marine Corps, especially CPAC likes to loose records... Honestly, I think it's hobby of theirs. The Military in general buy the cheapest Dell's out there that are always crashing, and you know TriCare and those folks in the DEERS office just need to see a piece of 80 bond under their noses to get anything done. I can't tell you how many times CPAC and TriCare have lost our paperwork.
