Trivia
There is a tribute to Airplane! during the Hostage Rescue mission. When the screen loads one man can be overheard saying, "Surely you can't be serious?", with the other man replying "I'm serious..and don't call me Shirley".

On the multiplayer map "Vacant", in the outside area, a truck is parked. Its licence plate reads: "Я3T4ЯD0", obviously a nod to the word "retardo", which is slang for "retard".
