What is the song played at the very beginning of Tropic Thunder when the 3 helicopters are flying over the jungle?

The song played at the beginning of "Tropic Thunder" during the helicopter scene is "The Real Slim Shady" by Eminem. However, it is important to note that this scene is often remembered for its intense and comedic portrayal of war films rather than the specific song. The juxtaposition of the upbeat music with the serious imagery adds to the film's satirical tone.
