Guess the film (theatrical or tv; or tv-series episode)?...

From these three clues guess this film (theatrical or made-for-tv; or tv-series episode):

1. Robert Duvall < The biggest clue.

2. Rocket-launcher.

3. Oil Tanker < Truck, not ship.

Two new clues:

4. Not Falling Down.

5. Not The Killer Elite.

This was made before both of those.

Two new clues:

6. Not 'Combat': "The Enemy". < Made after that but before The Killer Elite.

7. TV-series episode, not a movie (theatrical or made-for-tv film).

You may cheat and use Google (I know you will since you have no idea what this is).
