In this addition to the COD series, there are several missions where the player takes part in the faction known as Task Force 141. Formerly an elite special operations unit, they have since been disavowed for killing an American general (unbeknownst to the rest of the world, he was a traitor).
Throughout the game, TF 141 is able to enter multiple countries with a large variety of weapons and aircraft. Their soldiers are mostly SAS veterans with extensive connections. Even so, how could they possibly stay supplied with so much hardware given their red tape status and lack of government backing?
Yes I know it's a video game...but it still bugs me.
