Reviews of "Objective, Burma!" were generally favorable, although it was commonly faulted as being too long. "The New York Times" wrote: "This is without question one of the best war films yet made in Hollywood. There are no phony heroics by Errol Flynn or any of the other members of a uniformly excellent cast. These boys conduct themselves like real soldiers and even the newspaper correspondent is a credit to the craft. The Warners have erred only in the film's excessive length. It runs approximately two hours and twenty minutes, or roughly thirty minutes more than appears to be absolutely necessary."
