You, Price, Ghost, Soap, and Gaz were on a mission. They needed to get into a building full of important people that was guarded by several people and more inside.

Price: "Well we gotta figure out a way to get in there or this whole thing is over."

Then you walked away from Price and the others over to the security and they moved out of the way to let you in.

Ghost: "What in the bloody hell."
