 CONT: Throughout the movie, Lt. Dunbar wears the yellow shoulder  boards of a cavalry officer on his army jacket. In the scenes  leading up to just before the Sioux war party leaves camp to attack  the Pawnee, Lt. Dunbar has traded this jacket with Wind In His Hair  for a breast plate. In the next sequence, the Sioux war party is  leaving camp to attack the Pawnee and Wind In His Hair is seen  wearing this jacket while on horseback, but the shoulder boards on  it are now blue, the color worn by infantry officers.
