The emergency serivces detail lays a wreath in honor of those killed in the attacks on 9/11. Two members of the detail were in service dress, representing garrison duty and the responsibility to protect their countrymen and women at home, while the other two members were in full combat uniform representing wartime duty and the responsibility to protect not only their homelands, but also the homelands of those incapable of defending themselves.
