"From 'A Tolkienist's Perspective Blog' : a two part article part 1 part 2 about the military structure in Mordor. There is a hierarchy chart if you want a summary.
Was the rapid collapse of the military following the destruction of the ring indicative of the fragility of this structure , and its susceptibility to a decapitation strike ? Would a flatter hierarchy or something similar to the Imperial Military or Starfleet have been more resilient?"

This seems pretty speculative. The Orcs from Minas Morgul and the Cirith Ungol orcs do fight one another yes, but the book makes it pretty clear that this infighting is principally sue to the presence of the ring, and to a lesser but important extent due to the general tribalism and treachery among the orcs themselves. There's another instance of infighting earlier in the two-towers, and I believe in the Hobbit also if I remember correctly.
But to suggest that Minas Morgul went to war with Barad-dur is a bit of a stretch. Still, it put me in mind to read the books again to confirm things.
P.S.
A lot of Mordor military structure probably comes from the structures of old Numenor -- the Black Numenoreans military which conquered subdued most of Middle Earth and even Sauron himself at one point. Not to mention the fact that former Numenorean generals ( the Nazgul) are in command of the Dark Lords armys. But enough fanwanking for now I think.
