Norway tested self propelled artillery in deep snow and the Korean solution won, so they bought that. Other countries followed. Anyway, many of these products have components from all over the world and can also be customized like use a different engine or gun barrel. Furthermore, one can cross-use them like fire rounds made elsewhere. The key is to design for common standards like gun calibre or missile size so allies and partners can share. May the best ones win.
