Buster, that article (which itself has issues) and I are talking about two different things.
I am talking about the number of separate incidents involving friendly military personnel - they are talking about "total numbers killed" including civilians (which the B-1 has primarily due to one 97-fatality incident) and "civilian fatalities per 100 missions".
Neither addresses my point - which was to reply to PN's claim that the A-10 had no record of "friendly fire" incidents.
In respect to "blue-on-blue" incidents involving allied military forces on the ground (NOT civilians) the A-10 does have the greatest number of separate incidents.
