'Warfighter' is not a useful word, in my opinion. Where do you draw the line between 'warfighter' and 'non-warfighter'? Chinook crews? C17 crews? Voyager crews? Engineers? Fighter controllers (sorry, ABMs)? Loggies? Adminers? Wherever you draw the line, it's just as divisive as 'aircrew' vs 'blunties' - so in the modern, inclusively-minded, fluffy way, most commanders seem to describe all their personnel as 'warfighters'. Might as well just call them 'military personnel' in good old plain English.
