How many military retirees are in the US?

An accurate number is unavailable due to the inability to reconcile the still-living amongst the WW2-Korean War survivors, and the recent (2013-2014-2015) sesquestration that is cutting 30% from the USMC-USN-US Army-AF active-duty ranks.
As of 2010 there are 525,494 officer and 1,391,748 enlisted retirees for a total of 1,917,242.
