My Mongol army has been featured on this blog quite a few times over the years - it was one of the first I started building back in 2011 or so, and it has seen plenty of action since, though usually in a fantasy guise. So, when I started leafing through the DBA army lists last year, I was pleased to see that I had already enough Mongols to serve as the core of a IV/35 Mongol Conquest list* - there were just a few units I could add to have all the available options, and one of them was an artillery piece.
Well, my dad happened to have a spare box of Zvezda Siege Machines - Kit 1, and I still had plenty of dismounted Mongols (also of Zvezda manufacture), so I decided it was time to put something together. I liked the look of the ballista better than the catapult, and from the sources I could find it appears the Mongols were happy to use any and all types of artillery, so that's what I went with. The kit was a little more fiddly than my usual fare, but it ended up fitting together pretty neatly.
