I think first what kind of team are we going to be? In real life Espionage from books I've read they do specialize so a team working in the Eastern Block collecting intelligence would be different than a team that starts insurgencies or takes out targets. General Ops teams are unheard of most have some focus and usually would have trained together so languages and some other facets are likely determined by the specialty of the team and the region to work in. For example in Russia we would all need to be fluent in Russian, in Eastern Germany both German (principle) and Russian. In Panama Spanish is handy.
Example: In Under Siege the bad guy took out targets and installations for the CIA. In Tailor of Panama the sleazy agent collected information. In 24 the agency just took out terrorist threats and did domestic security of the highest level but even there they had smaller speciialist teams.
So GM I suggest pick the setting, location and purpose of the team that will guide a-lot such as languages and I strongly suggest the same agency and nation, the National Security Agency has the broadest powers operating inside and outside the USA and has more secretive stuff than anyone.
And remember several AOK's may need to be added like Computer Specialist (web junky, programmer and hacker) was not around in the original game I think and the www did not exist so maybe I'll take the tech savey hacker/surveillance role, no Military Sci she will fight her battles with a computer and lots of nifty electronic bugs placed by other agents. I'm sure not every CIA agent knows martials arts or weapons besides maybe a basic self-defense course and basic handgun training, but hers would be a lower risk job. Saw Golden Eye and the sexy nerdy woman with a souped up lap-top is quite appealing to me as an archetype.
