I guess because this photo was found in the First Armored Division Association Bulletin, “Old Ironsides,”, No. 3, Vol. XV, Winter 1963 – 64 (Leo B. Connor, editor), the colloquial use of “’em” in “Ride ’em, Cowboy!” was a no-no for a photo caption.
Sgt Maj Robert H. Hileman, Hg Btry, 3/2nd artillery, is ready to take off for another hitch with the Honest Johns of the 1st Armored Division. With 18 years of service already behind him, he wasted no time in civil life. He is a Korean veteran and the Communication Chief of his battalion.
