were undertaken by those whose career path is, er, "security" and not some press ganged cook or techie with (or without) a chip on their shoulder.
Certainly when I was serving there was an unfortunate mind set among a small minority of those in, say, the clerical or technical trades that they were somehow divorced from the nasty "killing people" element of the armed forces. If any cook or techie has a problem with the idea that they may have to one day fire a weapon in anger, then perhaps it is time for them to consider their position and seek civilian employment.
Btw do you imply that those whose career path is, er, "security" are less valuable to the service than those career path is, er "cooking chips"?
