Act I - No Russian Call of Duty: MW2 Guide

Warning: this mission contains scenes inappropriate for some people. If during the beginning of the game, you chose not to participate in it, it will be skipped.

Wait for the elevator door to open. Head with the others to the group of people. Your companions will open fire - apart from the guards, all of the civilians will die #1. It's up to you if you want to shoot or not (the mission won't end with failure). Above all, try to eliminate the guards as they are armed and can damage you #2.

Follow Makarov, you will reach the basement #1. Once you're on the airstrip, the Federal Security Service will show up #2. Don't waste normal ammo, their shields protect them very well. The grenade launcher will get the job done nicely.

Use the jet bridges supports and everything else as cover. Don't rush, move forward very slowly. Look out for one of the higher rooms #1. After getting rid of the enemies, follow Makarov until you reach an ambulance #2.
