When they are attending the outdoor wedding, Colonel Eugene Drake (Lee Tergesen) is shown wearing his US Army dress blue uniform. He is not wearing a hat. It is a regulation across all uniformed services in the United States that uniformed personnel must be wearing the appropriate cover for their respective uniforms when outdoors, and that they uncover when entering a building, unless under arms. The Colonel should be wearing the combination cover, the brimmed at with gold oak leaf sprigs on the visor indicative of his rank, that matches his dress blues.
