This is a good Clint Eastwood vehicle as the soon to retire Marine sergeant who goes back to the base where he started. He has several reasons, personal and professional, it seems.
He gets an eight-ball platoon to whip into shape and a good part of the flick covers his gradual success to make marines of his unit.
He has to fight off a hostile CO and win back his ex at the same time.
The war part included the invasion of Grenada and the sharp little combat there. This is worth your time.
