Song Be River in D Zone, 30 miles northeast of Saigon, Vietnam on Sept. 30, 1966. The 173rd Airborne Brigade began Operation Sioux City with several helicopter assaults. Boats followed the troops and an hour later a company of the 2nd Bn 503rd Infantry Airborne Brigade headed north across the 150 feet wide, fast flowing river, in rubber boats with outboard engines under cover of machine guns and air strikes. I was deployed with the 173rd on Operation Siuox City 1966. I deployed with D16 Armor.
