I wanted to draw attention to the HEAT shootout scene because it is excellent, and demonstrates, in a Hollywood way, some break contact drills, initially from a vehicle, then dismounted.
HEAT Shootout Scene (This is not the best quality YouTube example, but the good one appears to have been taken down)
It a great scene, there is so much to it. It was choreographed by “Andy MacNab” of Bravo Two Zero fame, first Gulf War, retired from the British SAS. There is more on the training here:
It incorporates vehicle and dismounted break contact drills. Initially they try and get away in the vehicle, firing from inside it, which you can do from a soft skinned vehicle. Then the vehicle is immobilized (driver shot) and they dismount and try to fight off the “X” utilizing fire and movement. The drills are great, changing mags, shouting “MOVE”, fire and movement until they split up, but then Kilmer and De Niro still buddy pair together, then Kilmer becomes ‘man down”.
They have to initally fire in both directions once they get out of the vehicle, showing the 360 degree nature of the threat. There is actually a lot in this clip and although it is scripted for a movie the tactics behind it are genuine break contact drills.
