This late-1800s Lakota warrior demonstrates his bravery through his conquest of war: a US cavalry bugler's coat (denoted by the stripes). Bugler’s coats were highly prized by the Lakota because the army’s buglers were seen as having "big medicine" - the Lakota interpreted the bugler’s role as one of fearlessness, since since they rode into battle without bearing arms.
In a bit of historical irony, the bugler was the usually the youngest and least experienced of the cavalrymen. (Although, perhaps that did, indeed, make him the bravest warrior on the field.)
