All my Sassanid infantry - three ranks of spearmen, supported by a rank of archers - 96 figures in all. Actually, it's four units - two units of 36 spearmen, and two units of twelve archers, but I thought they'd look spectacular displayed like this!
I've just had an idea. I might paint a unit of Roman auxilia with the same flesh colour as I've been painting Sassanids (and arabs) - so as to represent a unit raised and/or recruiting locally (i.e. in Syria). That should make it look a bit different!
