How to Get Dog Tags
To get a dog tag from a soldier, sneak up behind them, and aim your weapon while in First-Person view. Your character will then say "Freeze!" and the enemy will put his hands up. Run around to his front and aim at his face or "man-tools" to make him shake and drop his dog tag and other items. Be careful though, if you take your gun off him, they will attack.
Disable Enemy Communication
Enemies communicate and call for help by using a radio. They carry it on their back around the waste. If you shoot it, the radio will not work, and they can't call for help. However, they will try to run to get someone.

Throughout the fight against Vamp, he dives into the water and swims around. Throw a couple grenades in it and it will hurt him and take away health. Also, when he comes out of the water, he tends to go onto a certain point on the bridge and he kneels down. Lay a C4 or claymore here to damage him. Then, for head to head combat, use the Stinger missile.
Wake Up Sleeping/Knocked Out People
To quickly wake up someone who is either knocked out or sleeping, spray Coolant into their face.
Temporarily Knock Out Someone
When an enemy sees you, hears something, or is confused, an exclamation mark or question mark will appear above their head. If you quickly shot the symbol, the soldier will daze out for a little while.
On the Tanker, find one of the posters of the girls. Look at it in first person view then contact Octagon. Also, on the Plant, shoot a few of the seagulls to get yelled at by Colonel and Rose.
