The Task Force 141 and Los Vaqueros were on a mission to locate and predict Makarov's plan; they needed to stay low to not get caught. So, they have no choice but to invade someone's house to work on high technology to locate Makarov. This may take a few days...

They go to a random person's house. Price rings the doorbell, and the owner of the house opens the door.

"Sorry to bother you, but we are here to get our mission done." Price said. Price then invites himself inside with others.
