I think it could be because you don't have any weapons enabled for soldier class. There is a slight difference with silEnT against other mods, as we don't default enable SMG weapons for soldiers. I.e. if you don't have any heawy weapons enabled but want to enable soldiers with SMG weapons, look at g_classWeapons http://mygamingtalk.com/wiki/Silent_Mod_Server_Cvar#g_classWeapons Just a guess. I don't remember but I don't think there is a specific cvar to disable the soldier class, but it is based on disabling all the weapons from them.
EDIT: I just realized that we do default enable the SMG weapons for soldiers, because that is the way people got used to them, but there is a cvar option to disable those never the less.
