An Air Force sergeant is under investigation after a profanity-laced Facebook tirade in which she denigrated “black females” who are of lower rank than her.

Tech Sgt Geraldine Lovely has been “removed from her supervisory role” after the Facebook post went viral over the weekend, officials at Nellis Air Force Base near Las Vegas have said.

“It pisses me the f*** off that they have no respect and constantly have attitude,” Ms Lovely says in the video. “What the f*** is up with that?”

A version of the video uploaded Monday was viewed more than 900,000 times, according to the Las Vegas Sun. In that video, Ms Lovely was wearing her Air Force uniform.

“They’re talking down to me. I’m trying to tread lightly as a higher-ranking (non-commissioned officer) to not blow the f*** up and start a fight club,” she says in the video.

“Every time I f***ing talk to them, it’s like I’m just some stupid a** girl that doesn’t even deserve to be talked to as a person,” she continues.

The Air Force base said that they will be using the profane video to start a dialogue within their ranks.

“While the actions of this individual are inappropriate and unacceptable, we are using this information to continue a dialogue with our Airmen about the topic of good order and discipline,” an official form the base said in a statement.

Ms Lovely works at the base’s fitness centre as an administrator, according to an official. She deleted the video after receiving complaints that it was racist.
