I was a Medic, not a Cav scout so I cant tell you to exactly what they do. But having worked with both infantry and scouts they pretty much do the same thing. Scouts have a bit more training and can "operate further" behind lines. Infantry like to walk where ever they go and scouts will ride in a mile or 2 closer, then walk. LOL. When I was in Iraq infantry and cav scouts both did the same kind of jobs, both went on patrols, QRF, guard tower, etc etc. I think 1topp was a cav scout or he was with a cav unit. Get your spurs though, its fun from what I hear. LOL.
