To be fair, there's a plausible explanation for what robaato describes that doesn't involve corruption. Suppose it's standard or common to move things first and then file such "backdated transfer requests". After a fire that destroys everything in a warehouse, there would be a flurry of activity to quickly account for everything that was destroyed, so paperwork that would otherwise have trickled in over a month or two might suddenly be hurriedly filed in a few days.

It could just be lackadaisical administration that only gets urgently addressed when there is something perceived as a particular problem.

The military is not exactly known for being great at keeping track of things that aren't nuclear weapons, and sometimes falls short even on those.
