PANJWAI, AFGHANISTAN — U.S. Army Capt. Mike Aldrich hunches over his makeshift desk at Forward Operating Base Sperwan Ghar. He is the commander of Alpha Company, 1-16th Infantry Regiment, and currently nearing the end of a marathon 13 hour planning session. Functioning mainly on caffeine powders and poorly made coffee, the haggard officer is surrounded by a sea of crumpled notebook paper. On his walls are two white boards filled top to bottom with scratch work.
