Here is a link to the build log.
When I was building the Apocalypse tank I noticed parts of the exhaust were similar to the AMX-30 and parts of the plow system were similar to Pearson Engineering items. The Bundeswehr were actually testing a quad-track vehicle quite recently too so even that aspect of the design has a bit of inspiration from the real world. They were not as difficult to do as they look but a bit odd to do four track assemblies for one tank!
