The year is 2014. We have developed a new technology called 'Nanomachines' they help us stay in sync with our squad. They also prevent us from getting ill, diarrhea on the battlefield can slow ya' down. Another handy thing is they let only us use our weapons! Those resistance will just jam the guns if they try to fire them, handy huh! And get this, they prevent our emotions from coming through, well not all of them, just the bad ones, you see a teammate die meh you don't care! Anyway we work under Outer Heaven. Fight the resistance and obey orders.

The year is 2014. We fight those PMC d**ks, they have these 'Nanomachines' it makes them more advanced than us, we need to use old or un-reliable weapons. But we WILL win this war. They want to control us, we cannot let them.

We are the best of the best. We have nanomachines, the best weapons and we are the perfect squads. We fight to keep the peace, those PMC step out of line and use biological warfare we take them down.

You may have noticed your newest Nanomachines are a bit different, that because we gave you a power, now with our technology this power isnt too good, but it does the job. Our plan will come into action soon patriot, just obey my orders. ~Ocelot

We know you came from a bad beginning. You have no family, but we can avenge them, if you come with us we will give you a powerful suit. You will be our best soldiers, don't worry we are your friends ~Ocelot

In summary these guys are people in massive suits of armor (or not) who each have their own power/weapon.
