Farmers and herdsmen - who were tougher?

[Gesiþ]

I think that non nomadic pastoralists as John M Roberts mentioned like shepherds would make excellent light infantry as they would be skilled with sling & archery to ward off predators & rustlers & be pretty fit.

Also they would often be in a lower economical class, less able to afford medium-heavy equipment and would thus make an excellent recruitment pool for the Polybian-era Velites, or the Hellenistic Psiloi, for example.
