The "no surrender code" is based on nationalities. In the case of the USMC it's only the Japanese they won't surrender to. The Japanese will not surrender to anyone. The game has been this way for over 8 years now and has been noted in the game guide in ever release since then. However sometime in the past 5 years or so the surrender code for the USMC was refined to only not surrender to the Japanese. Previous to that it was everybody.
