Tank

Tank is a 1984 drama film starring James Garner (from The Great Escape primarily, but also the antagonist of Atlantis: The Lost Empire), Shirley Jones (The Partridge Family; Oklahoma) and C. Thomas Howell (Red Dawn), and also James Cromwell (Babe, Star Trek: First Contact, The Green Mile, Space Cowboys, The Sum of All Fears, I Robot, The Longest Yard and Surrogates) and G. D. Spradlin (The Godfather Part II and Apocalypse Now) as The Dragon and the Corrupt Cop, respectively.

Tank has examples of:

 * A Father to His Men: And to his kid, and to other people's kids.
 * Corrupt Cop: Sherrif Cyrus Buelton. And everyone else.
 * Corrupt Hick: Major Zak Carey gets on the bad side of one of these, who ends up framing his son for drug possession and cheating him out of his retirement money. Garner's character, however, is a Sergeant Major in the Army -- literally almost a Retired Badass- - and owns a fully restored, fully armed WWII Sherman tank. Hilarity Ensues.
 * Dirt Forcefield: Works on Bill's skin, but not his clothing.
 * Good Ol' Boy: Cyrus. The trope is even referenced by name.
 * Hooker with a Heart of Gold: Sarah.
 * Lock and Load Montage:
 * Military Brat: Bill and (the dead) John.
 * Military Maverick: Subverted; Zack is all for keeping the peace in the armed forces.
 * One-Man Army
 * Papa Wolf: Shown zealously earlier on.
 * Prison Rape:
 * Tank Goodness: It's in the name.
 * Was It Really Worth It?
