There are no enemies on ME that can provide the use of such tactics. No flying enemies (Mantis gunships and drones don't count because they're almost always stationary), no enemies that require shooting in a specific spot in order to damage it, none that can become more dangerous when allies are killed or when heavily damaged, etc.
