[Rainbow Six]

I also like the concept. I can't recall off hand how far south the Soviets got when they pushed down the Pacific coast, but might be an idea to have the marauders being a mixed bunch of Canadians and Soviets, with the odd American thrown in for good measure? Maybe the tanks could be Soviet (and you could add a few more armoured vehicles)? or swap one or more of the tanks for a Shilka - I'm not familiar with the geography, but a Shilka parked by one of the bridges on the island side might be an effective deterrent against an attack.

And maybe have two of the bridges either destroyed completely or rendered impassable (mines, booby traps, etc) so the marauders can better control access to the island?

With regard to fleshing it out, a few thoughts....who's in charge? One individual or several leaders? Maybe an alliance between a local Canadian strongman and a Soviet Army officer? Does the strongman have a connection with the airport? Maybe he worked there (baggage handler, airport security guard, etc) What sort of facilities are available? Bars? Brothels? Gambling dens? The marauders have to eat - are the local populace semi willing accomplices (sounds like things could be worse for them) so provide the group with basic services (food production, laundry, cooking, other more "personal' services, etc) in exchange for a degree of security?

Any planes still there? Sure, they'd likely be non operational but could they be restored to some semblance of working order? Not neccessarily 747 or widebodied airbuses, was thinking more the smaller commuter jets / turboprops used by the likes of Air Canada Express (probably wasn't called that then...). Is there an onsite Hotel that the marauders could be using as living quarters? if not where are the offsite Hotels? On the islnd or the mainland?

Just a few random thoughts...
