Alright, I'm going to throw in some of my knowledge to the situation.
I know Moose, knew him quite well. I was there for his interview for Taggart and I worked alongside him at one point in the Special Operations. He worked extremely hard on documentation work and he never seemed to be a guy to throw away the work he's done.
And out of my view, I have no idea how the documentation was lost or "deleted" but all I know from Dargon and Arcann about the Commando documents is that we had to completely remake some documentation. Little to my knowledge and I'm sure either Arcann or Dargon could point this out as well, I never knew anything about a Sergeant document for the SC, nor did I know of any of these documents Moose owned except for the Tryout Document.
I would like you (Moose) to please speak with Joah/Zim or the Directors about something like this and prove yourself that you didn't delete this documents and explain to them where these documents went when Taggart's were being chosen.
This doesn't seem to be a +1 -1 situation, so I'll leave it at that.
