Early in the Clone Wars, clone captains in the GAR were identified by red markings on their armor, while Imperial Army captains seem to have typically worn an insignia with three red pips over three blue, and one code cylinder at the left shoulder, although it seems that in some situations, other variations were known: for instance, a Rebel source indicates that some Army captains aboard the Death Star may have worn a rank bar with a single strip of three pips, and one rank cylinder at either shoulder.
