Alejandro Rojas

Rojas is an arms dealer in Call of Duty: Modern Warfare 2. He lives in Rio de Janeiro (Brazil), and is protected by the local militia. He is also a contact of Makarov which is the reason he attracted the attention of the Task Force 141. In the Worldwide trailer, two men approach Rojas with one of them with a pistol (Most likely Desert Eagle) and Rojas pretends to surrender then steals the pistol and shoots the 2 men with another man looking at what's happening. Rojas then spots him and tries to shoot him. Later in the trailer, he is running down the streets with a weapon like in the Rio De Janiero gameplay video.

Trivia

 * The way Task Force 141 chase after Rojas is very similar to how Captain Price and his team were chasing Victor Zakhaev in Call Of Duty 4: Modern Warfare.
