H. P. S. Greene, In the line of duty (1928)
“ Why weren’t you drilling them yourself?” “Why,” blurted Tommy, “I don’t know how to drill ’em. I never drilled anybody in my life!” “What? You, a commissioned officer in the United States Army, stand there and admit that you are not capable of drilling the men under your command? Well, sir, you are hereby relieved from that command. Remove yourself and your belongings from the 946th Squadron’s barrack at once, to make room for your successor. And, young man, remember this: Never give ‘You don’t know how’ as an excuse in the United States Army. If you don’t know how, learn how! ”
