Call of Duty: Modern Warfare 2 Achievements / Trophies

Pit Boss

Take the 2 Red Dot rifles for easier aiming. You can get a 2sec plus time bonus for high accuracy. Use short bursts and you will have enough ammo to clear the building. Switch guns as you head upstairs and melee the first tango. Clear the room, drop out of the building and work your way back to the left side. Sprint the final section. If you missed anyone or killed any civilians you will get a MAJOR time penalty. If you don't get it, you can re-run the course.

Colonel Sanderson

Near the end of The Hornet's Nest you will come to a crowded market place with a LOT of chickens in cages. Clear the entire area of enemies first. Then after you team has moved forward there are several sets of 6+ chickens. This will of course depend on the amount of damage you did in the battle. I did this on Veteran and still found plenty of chickens to kill. If you have grenades left all the better. Find a group of at least 4 to toss a grenade at and then be ready to fire on another group as soon as the grenade goes off. If you are having problems, play through the level again on Easy. The battle will be easier and the collateral chicken damage should be less.
