hey guys just a quickie should I deploy a unit if 20 skink skirmishers or 2 x 10 skirmishers? cheers in advance.
You would probably be better off doing 2 units of 10. If you do run them in 20, make sure that to try to keep them in ranks of 10 (which will make the unit fairly long and unwieldy). That way, you can shoot all of them.
I would second this. Since you can't "blob" the skirmishers they get sort of unruly in their large formations.
