This is Lieutenant General (retired) Harold "Hal" Moore. This picture was taken when he was a Major General and the Commanding General of the 7th Infantry Division (Light). As a Lieutenant Colonel, Hal Moore commanded the famous 7th Cavalry Regiment at the Battle of Ia Drang on November 14, 1965, which was the first major force-on-force engagement between the forces of North Vietnam and the United States. His 1992 book, "We Were Soldiers Once...And Young" (written with reporter Joe Galloway, who was also present at the battle) was required reading for those in leadership positions in my Airborne Infantry unit a few years after it was published. I read it several times myself before the movie came out, wherein Mel Gibson played Moore.
This man is a legend among professional soldiers, and has been a personal hero of mine since my Army days. He died yesterday, Feb. 10, 2017, aged 94 years. The cliche "they don't make 'em like that any more" isn't so cliche here, and I'm reminded of a line from Hamlet, Act 1, I think Scene 2: He was a man. Take him for all and all. I shall not look upon his like again.
