After watching the trench scene for about the 10th time in the last 2 days (only a couple times for trivia purposes, the rest because it's just an awesome scene) I decided to check the credits to see how many "Reds" are listed

There are only 5...
Red Leader - Drewe Hemley
Red Two (Wedge) - Dennis Lawson
Red Three (Biggs) - Garrick Hagon
Red Four (John "D") - Jack Klaff
Red Six (Porkins) - William Hootkins

Who is this Red Four guy? John "D"?? He's not seen or mentioned in the scene at all! And yet, there he is...maybe he was in an original cut, and but found the cutting room floor later....oh well...an interesting tidbit...

My answer stands, cuz there was 9 Reds mentioned in the scene.
