Overt racism was typical in American bases in Vietnam. Although initially uncommon at the start of the war, after the Assassination of Martin Luther King Jr., overt racism occurred at a higher rate. Following the assassination, some White troops at Cam Ranh Base wore Ku Klux Klan robes and paraded around the base. At least three instances of cross burning were confirmed to have happened. Da Nang Air Base flew the Confederate flag for three days in response. In addition to being used in response to King's murder, Confederate flags and icons were commonly painted on jeeps, tanks, and helicopters; bathroom graffiti proclaimed that African Americans, not the Vietnamese, were the real enemy. Black troops were discouraged from taking pride in Black identity, with one troop ordered to remove a "Black is beautiful" poster from his locker. Following complaints from African American soldiers, Confederate flags were briefly banned but soon allowed after resistance from Southern politicians objected. Black identity publications and speeches were restricted, with some commanders banning recordings of speeches by Malcolm X or the newspaper "The Black Panther". Despite segregation being abolished in the military, it still affected troops.
