The correct answer is the last one: African American soldiers were more likely than others to serve in combat positons during the Vietnam War. In fact, statistics gathered from the time show that in 1968 although African Americans made up 12% of total Army and Marine numbers they contributed more than 50% of the front line combat troops. This was a clear disparity that was worked to reverse as the war progressed. Still, many argue that African American soldiers shouldered an unfair burden of loss during the Vietnam War.
