modern warfare 3 doesnt have it to my knowledge, its a non realistic game. I havent played battlefield 3, but I do know that you use actual military tactics instead of running around doing spray and pray. Hope that helps...
I think he may have been pulling your leg. I've played both of those and wouldn't call anything included in either of them training. You could try America's Army though, if it still exists. It's a pretty decent game that actually makes you take short classes before you can be qualified on certain things(airborne, sf).I don't think it had anything in regards to cff, but then again I haven't played it since 2006.
