This is truly the best military comedy ever made. It is funny, yet it realistically depicts the savagery of war and the non-chalance it gradually inspires in its victims. For example, some of the funniest, yet also most disturbing, moments in the film come when the doctors are operating on wounded soldiers, complete with gruesome sound effects, yet are discussing extremely trivial matters.
The film also benefits from some great performances. Donald Sutherland and Elliot Gould were excellent as Hawkeye and Trapper John. They both had a streak of good movies during the 70s. Robert Duvall is amusing as a pious major whose fanaticism drives our heroes to extreme measures. Sally Kellerman and Tom Skerrit also put in good performances in their roles; it is a pity that these two actors are not better utilized nowadays.
