Former Secretary of Defense, Robert McNamara, died today at the age of 93. He arguably was more responsible than any other person for the adoption of the M-16 as the standard long gun for all branches of the military. The Air Force had adopted the M-16 in 1962, but it was McNamara who approved the adoption of that weapon several years later for all branches of the military. It was largely a move toward greater efficiency in the military, based on an industrial philosophy he had used successfully at Ford Motor Co. Goodbye .308, hello .223. That decision has consequences today, including the prevalence of AR-15s in the gun safes of many members of this forum. Like him or not, he was a guy who influenced history.
