Hi dvv...
I take your point -- which is why I specifically wrote I was not saying that software or database inaccuracties did, or did not, play a part in this accident,
Having said that, virtually all of the world's militaries use civilian manufactured and certified (on-board) navigation equipment. Military transport aircraft -- especially those that carry VIP's -- spend most of their time in civilian airspace, under civil ATC, and operating into and out of civil airports. We don't yet know what nav systems / equipment this particular aircraft was using, but I'll bet you a case of beer that the databases and software were civilian manufactured and (hopefully) certified.
