How do you do missions on combat arms

If this is a recent question, you do the missions by receiving and solving hints. An example is 'afraid of heights'. Thinking breifliy on it, a verb of tha is Vertigo, which is a map. Play elimination, get 50 kills, and you've solved mission 5 (hint 5). Another one is 'man overboard'. The only map with an ocean on it (man overboard is what they yelled when a sailor fell off the ship) is the new map called Oil Rig. I believe you need to play one man army for that mission.
