Well I'm not sure if there is any way to tell to the engine, where to spawn which players?!
Try to enter the game (create the map) several time joining the same team every time (germans), then several time joining (americans). And see if you are getting spawned on the same side every time. Maybe engine spawns on the same side every first time you entering the map, or it depends on the team)
This way you will know which way engine works! Random or team defined!

Dotn forget to exit the game to windows every time. So for each joining, you must start the game from the beginning (desktop shortcut, COD2MP.exe)
