I think there is no point. This looks like a pilot for a one-hour war drama like COMBAT! that never got beyond this stage. Filled with Cold War angst about the forthcoming Third World War, we watch as shots of Americans with guns alternate with shots of Japanese with guns, eked out with occasional shots of palm trees, until the fighting is past. "Poor slobs" the Yanks announce about the dead Japs, until the Japs, not quite dead, start shooting.
This is the earliest instance I have encountered of the Racially Integrated World War Two Combat Unit, which is a nice thing when it comes to acting jobs for Blacks and racial harmony, but is historically nonsense. U.S. military units were segregated by order of that *great* humanitarian Woodrow Wilson and integration did not begin to take place until an executive order during the Korean War by Harry Truman, alleged KKK member.
Director Kowalski later went on to helm some good episodes of COLUMBO, so either this wasn't his métier or he needed a decent script and actors or he learned how to direct as he went along. Whatever.
