Now some random stuff.
Formations 725 and 726, Recalled Republican guard.
I do vaguely remember the issue being raised at some point during either the Garner or Bremer administration with the intent to use them to restore order, but nothing was done of it, given the uproar it would have caused. They should be deleted.
Formation 749, Guer Tanks (Guerilla tanks).
There are no reports of the post 2003 insurgents having ever used armored vehicles (there are a few reports of some technicals but that's it). The Peshmerga had some tanks but that since much before 2003, presumably captured during the 1991 struggles.
This is an old example (I can dig more recent pictures if you are interested).

So this formation should be either deleted or made available much earlier.
