Artillery ... so i don't just need to use models from non-manufacturer producers which coincidentally make artillery models i can use. Especially Figures using this siege & field engines will be fine.

Regarding to standard figures i miss poses which refer to the statet narratives: If a mongol falls from his horse, he begins to shoot around himself with his bow immediately.

Or poses whih show how a light horseman wield his hooked lance.
I especially like the Zvezda pose of a man having his lance thrown over at his back whilst using a bow, that could be done for a non-armoured rider too.
