Interesting, in some countries it is common popular belief (thanks to media BS), that "contractor losses are not accounted", etc...

Well... not really.

It would be good if we could find a source for information on Operatives/Contractors killed while on duty. I think I mentioned before to Ted about a `Memorial Wall` thread but finding the info is proving quite difficult.

We already have a section for operators killed:

We need to find a source of info as you rightly point out.
