Warr As a senior first lieutenant at Fort Lewis, I suffered a terrible humiliation. We all know the dangers of the M2 Flex HB cal .50 Machinegun. Despite all the warnings, in prepration for an impending CMMI during an arms room inspection I did the unthinkable and spent the next two weeks in McChord AFB hospital recovering from a thoroughly pulverized toe (those things are heavy). Worse, I had three roommates who had crashed helicopters in Vietnam.
