the Department of Defense, whose .mil account holders have been very busy on Wikipedia. The defense agency with the most edits originating from its .mil address is Army’s Network Information Center, with 43,823 edits. The U.S. Air Forces comes in second with 21,478 edits, while the Naval Surface Warfare Center has 18, 591. The numbers drop dramatically from there with fourth and fifth place going to the Pentagon overall and the Office of the Secretary of Defense at 3,355 and 2,685 edits, respectively.
It appears that the Leathernecks either don’t understand computers or don’t care about what is on Wikipedia, because according to VIRGIL.GRiffith‘s WikiScanner there have been only 30 edits from usmc.mil.
