Bruce Dern in a dual role?

Next time you check out this movie, take a good look at the scene where Maj. Falconer stops on his white horse to talk to a heavily bandaged officer on foot. Only his eyes, eyebrows, and nose can be seen but just by these there is a strong resemblance to Bruce Dern. Even his voice, which is obscured behind the bandages, resembles a soft spoken Dern. I've checked the credits and there is none given to whoever had this small speaking role which is unusual since some of the prostitutes who had less to say in their one line or two were given credit.

I'm guessing that since this movie was filmed in Yugoslavia, there was a lack of english speaking actors of the American dialect on hand and with bandages to disguise the face, Dern was choosen to fill in for a second role.
