I kinda completed the Special Forces Training with a little help
from GameFAQs 
But I sat thru the medic lecture and get 100% score without
external aid.
Only thing I don't bother is sniper training. (I mainly do a lot of
healing and hiding mostly, cause I'm a MEDIC!)
And yes, the Javelins are cool, Humvee a bit hard to drive, and I
like the co-op mode, if only those ppl on a public server can
cooperate and complete the mission, rather than trying to chiong
and kill the entire terror camp.
But my fav map is still SF_Hospital! I like being VIP, since I do a
lot of hiding, arm-rest grabbing jogging to the extraction point
and covert killing the entire enemy team when my team sucks.
