So, I'm planning my next session, and I have an idea for an adventure where the runners get hired by a Johnson from DocWagon. The setup is that DocWagon teams around Seattle have been getting ambushed; an armed group has been attacking and flat-lining high-paying DocWagon customers, wiping out the response teams and stealing their vehicles, which have vanished without a trace. The runners are being hired to put a stop to whoever's doing this and help DocWagon save face before these incidents become too public.
I've done a little reading on it, and according to older source material, a DocWagon HTR team consists of three medics and four security guys, in an armored Ares truck with roof-mounted machine gun armed with gel rounds. What I mainly need to know is, what Professional Rating should these DocWagon security guards be at? I was thinking somewhere between 3 and 5, and I need to create this team who's taking them out to be a little tougher than the DocWagon guys, but not so hard that they can't be dealt with my players. Any thoughts?
