Thanks,
After some searching in MW I have found the answer to my question, in the scenario editor one of the options from the <command> menu is <Toggle Civilian> Job done! :)
..This isnt't an option available in ToD, and I haven't looked at others in the SB series but imagine if it isn't in ToD it wont be in the others.
This would be a nice feature to have in all the SB games, it could make for some interesting small scale scenario designs, rescuing hostages, downed aircrew, prisoners etc.
..anyway back to the scenario editor in MW now to see what I can come up with..
