About UNATF, I always viewed that as our current UN military, which is anything but specialized and downright incompetent at times, especially without US support so I don't think they should be all that specialized.
Well, this is the future. In this future, I applied a few radical changes to the world. The European union is one country, the world uses a single currency, and nearly all countries are a part of the UN. The UN Security Council no longer has veto power, and the UN has been reformed to have more value in peace keeping. Organizations like NATO have been disolved in favor of this UN military. No countries really fight alone any more, the UN decides almost all conflict members will participate in. However, you'll also have to note this is not our main force, but rather the UNATF, a specialized sector of the UN Military which is highly trained and consists of many of the best soldiers from countries around the world, using technology from various member states (thus why a Russian RPO, a German tank, a British gun, and an American Missile Launcher can all co-exist in the same task force).
However, our opposing faction, the cult, does not come from any sole country either. It is a collection of terrorists who do not agree with the increasingly democratic movement of the world, wanting to further their own agenda. Funded by secretive supporters, they have access to comparable weaponry, and worse: they are not limited by the UN's rules, which now outlaw most weapons of mass destruction, barring Nukes, which are the sole remainder for the concept of balancing the few countries that are not UN members, but are now nuclear armed. The cult's scientists, which include some very effective scientists, since most other countries stopped all chemical and biological research programs, have managed to create a neurotoxin which brainwashes victims, turning them into blood thirsty cannibals with no regard for life and no feelings of pain (or anything else for that matter). Essentially, they just started a zombie apocalypse. But why is the cult opposing the rest of the world? They believe that the world has been brainwashed by "western" ideals, and believe the only way to solve this is to destroy the world and start anew. Kill everyone but a few, repopulate the world, and rebuild it their way.
Hopefully that explains the back story well enough. Yes, a lot has happened in these 20 or so years (the year will never be directly mentioned in scenarios now, instead opting for military style timing and dating for determining the "time" into a mission). And yeah, UNATF is really quite like Star Treck's Section 31, but the difference is that it does have rules it has to follow, but those rules are to protect the civilians. After all, the UNATF is the "good guys" while the cult is the "bad guys". Of course, you could play as either (who didn't secretly enjoy the airport scene of MW2 anyway?).
I am personally leaning towards "Apocalyptic Dawn" as the name for the techtree, unless anyone else has better ideas or a reason to oppose.
