It is a great link, although I believe it's possible Lineberry sometimes tries too hard to find meaning when a line is just there.

I remember when I was in S Korea during joint exercises and hearing the (mostly) Army guys singing for PT. Also in Kuwait. I figured, because they usually only sang when they ran in these places, one would have to run along behind them with a tape recorder to collect the songs.

The nice thing about military cadences is they never have been, and likely never will be, influenced by collectors or folklorists. The songs pop up in enormous numbers and variation, and people sing whatever they want. So "Doo Wah Diddy" gets adopted because it's in "Stripes" and the guys like it, or somebody writes a whole new song and the guys like it. Of course, the standards will remain
