Since their only goal is to prop up Assad and increase their own presence in Syria, that is easy to understand. As I'm sure you are full aware, Russia is not bothered by niceties, like 'rules of war'.I think the Russians know more of what they're doing in Syria than the US ever has.
The West (including the US) doesn't really have a goal in mind, other than to overthrow Assad.
