Black Unity was a newspaper published out of Vista, California, with an intended audience of Black servicemembers, specifically Marines at Camp Pendleton. The newpaper appears to be an indirect descendent of Attitude Check, and published as a sister newspaper to All Ready On the LEFT, which had (perhaps) an audience of white Marines stationed at Camp Pendleton. Both Black Unity and All Ready On the LEFT gave directions to a house in Oceanside that was known to be a meeting spot for servicemen that were politically left. Each paper also contained this note, indicating there was a split from the Movement for a Democratic Military (MDM):

"The reason why MDM separated and Attitude Check won't be around any more is because we weren't getting the full support of the people. Third World people (black, brown, red, and yellow) couldn't relate to it because they thought it was a white organization. White people couldn't relate to it because they thought it was a black struggle. We are all struggling to reach the same goals, but we each have to organize our own people first. Once we organize among ourselves, then we can unite. Until all of us are free none of us will be free."
