It was on cable about 5-6 months ago, I believe. Australian commandos in WWII, if I recall. I didn't get to watch the whole thing, but I remember a scene where they arrive in-country and one of them gets wounded. Gibson and the others go on and the wounded guy stays back with a teammate. He has a smoke, and is then shot dead by his 'mate, who rejoins the rest of the squad, and they proceed with their mission. Harsh.
