Having seen it, is there still any reason to see the movie? Or is that the gist of it? Because from looking at Wikipedia, that looks like the gist of it.
Absolutely; this montage captures the essence of the plot, but watching it unfold is still quite entertaining.
Edit: The clip is really more of a flashback -- the rest of the film deals with the young officer trying to ensure the vehicle receives a live fire test.
You'll miss the goats, the burning mannequins, rockets being thrown of a lift onto a crane on a tank, the toaster bolted onto a tank and the grand finale.
Also you'll miss the fact that everyone except the guy that said what would happen got promoted and he retired prematurely.
