Here's a few FC2 tips:
-When you first start the game after a long breaak, spend some time getting used to how it plays.
-If you have less than 3 bars of health, jab yourself w/the syrettes
-Best assault rifle is probably the AK-47 as it doesn't cot much to buy and upgrade and you get it early on.
-If you don't have the Light Assault Bandoliers, don't bother with the Mac11 or Uzi.
-the M-79 is a great anti-vehicle and personnel weapon, and has a quicker reload than the rpg's
-cars are precious, so if you have one and aren't near a guard post or safehouse, don't lose your one.
-beware of the grenade laucher vehicles, and if you don't have one yourself, and an enemy attacks you woth theirs, take it from them.
-if you're inexperianced, always do what you're buddies tell you, if you don't you'll be stuck in long firefights
-the dart rifle's good, but get the reliability upgrade for it
I'll update this as more tips come to mind, 'til then, enjoy!
