If your scout got Scouting III, they'd get five or six hexes of movement on hills!
Seriously if you can get a fully-promoted Scout into an Archer it's the best unit you will have period. Mad defense that makes Bowmen look fragile, ever-useful Medic, buckets of sight and three terrain-ignoring movement. Throw Fountain of Youth and Kilimanjaro in the mix and auuuughwtf
