Ah skirmishers, the most disposable of all infantry. But you’ve got to have them, and in somewhat realistic quantities.
I painted the guys with javelins about a year ago, but the slingers were left languishing in the painting queue. For no particular reason I grabbed them out recently and threw some paint at them. Actually, there was a reason: I was looking for something quick and easy to paint to get myself back in the groove. You can’t get much easier than medieval peasants: they’re just a tunic and some leggings and skin without any decorative bits at all.
You can really see the time delay between these two units in how differently the photos were shot!
