The Commands and Colors rules for "auxilia" seem written with classical peltasts in mind. These troops can fight as close-order infantry or skirmish with javelins.
I used the same figures for the Greek psiloi, or light foot
My Commands and Colors scenarios call for two units of Persian slingers, and here they are! The slingers get an extra hex of range over the standard light infantry.
I went for more drab colors on these troops. I'm not sold on the idea of slingers with shields, but that's how they came.
