During our time embedded with the troops in Afghanistan a few months back we noticed there were lots of energy foods laying around everywhere we went. I actually lived on nothing more than Cliff Bars and Gatorade for a couple of days during our time with the 101st Airborne in Paktika Province. (And I felt fine, trust me on this one . . .) Whether sucking down gooey gels or chugging drinks that duplicate a pot of coffee's worth of caffeine in a single small can, our warriors are definitely leveraging the power of modern "nutrition" to stay trigger-tugging ready.
