I'm not sure what the discrepancy in reporting is.
For example I'm not getting those numbers for defense outlays at all.
Department of Defense outlays Q3 (FY2012Q4): http://www.fms.treas...mts/mts0912.pdf (page 32)

WTF?
A few ships going into the shipyards, along with a couple of armoured brigades and air wings going into maintence and upkeep could easily account for this difference. Not that I am saying that is the reason, but you have to dig into why.
For example, just to decommission the USS Enterprise is going to add a one time cost to the Navy's budger for 2013 of over 800 million dollars.
