While in Okinawa, before being deployed to Vietnam (in May 65), the 173d's commander was a big fan of the tv series "Rawhide," about a bunch of cowhands moving big herds of cattle, etc. Thus, the morning wake-up call (reveille) blaring out of huge speakers, was usually the sound track to Rawhide, 'head em, move em out, keep them doggies moving!--RAWHIDE!, RAWHIDE! (or something like that!).
Thus, they started calling themselves "The Herd."

In 1965, I was a sophomore in high school.
I grew up as an Army brat in Japan, 1951-1961. My dad worked for the Japan Procurement Agency in Tokyo, an Army/State Department outfit that bought things for the Army and Air Force in the Far East (Japan-Korea)and carried out a State Department charge to funnel US money into deserving Asian industries. In the early 1950s, Japanese truck maker Isuzu was near bankruptcy and wanted to make something--anything for the US Army. My dad brought in a brand new Dodge Duce & a Half truck from the states and Isuzu copied it exactly, right down to the tool kit. They returned to financial health by shipping these 2 1/2 ton trucks all over Asia, including Korea and Viet Nam for decades.
