a few years ago I nearly went to work as 'Security' for a company called Executive Outcomes.... a merc for hire company created to protect the DeBeers diamond mines in Africa. Pay was insane.... several hundreds of thousands of dollars for just a few months work.... but life expectancy for the not-so-quick or unlucky was roughy 7 days. Needless to say, it was enticing, but I took other options.
they're now defunct.
