Great war-comedy. Hilarious in its take on the silliness of the military, with a decent amount of drama thrown in. Reminiscent of MASH, the movie and the series, and Catch 22, the book (the movie adaptation was less good).
Great performances from an all-star cast. Casting is spot-on: Clint Eastwood as the hard-bitten, decisive, take-command Kelly; Telly Savalas as the tough sergeant; Donald Sutherland as the hilariously insane Oddball; Don Rickles as the deal-a-minute stores sergeant; Carroll O'Connor as the clueless general. Also includes Harry Dean Stanton in a relatively minor role.
Also has one of the best and most memorable theme songs of all time - "Burning Bridges" by the Mike Curb Congregation.
