"Those of us in the military may have even underestimated the degree of support the American people still afforded the military, for a recent public opinion survey revealed that the military services are among the public institutions that the people trust most. For one looking back on thirty-six years of service in the United States Army, that is a rewarding thought. So, too, I am struck, upon reflection, by the unprecedented changes that occurred during those thirty-six years. From the World War I Stokes mortar and the Model 1897 French 75 artillery piece to sophisticated guided missiles; from the model 1902 rifle to the M-16; from carrier pigeons and Morse code telegraphy to walkie-talkies, computers, and sensors; from a private's pay of $21 a month and a second lieutenant's of $125 to today's private's pay of $344 a month and today's second lieutenant's of $634; through three wars and a number of police actions; from volunteer army back to volunteer army; and from isolationism to multiple international commitments. As one in the middle of the changes at various levels of command responsibility, I have always been impressed by the loyalty, flexibility, durability, and overall effectiveness of the United States Army. The traumatic experience of Vietnam was no exception."
