This is one of those lists that will never be completed because GIs and civilians alike are constantly inventing new acronyms and abbreviations to shorten the English language. Combined with the standard (and not so standard) medical abbreviations, it's a wonder we speak whole words at all! A large number of the abbreviations in this list are dictated as part of military Board Examination reports, and are legitimate in this setting.
