The Royal Air Force is investigating an "offensive video" involving personnel.
A spokeswoman for the force said the RAF Police Special Investigation Branch is looking into the incident after the footage was obtained by the Daily Mail.
An RAF spokeswoman said: "We have been made aware of an offensive video involving Royal Air Force personnel.
"The RAF Police Special Investigation Branch is now investigating the incident shown in the video.
"It would be inappropriate to comment further while investigations are ongoing."
The RAF said it does not tolerate bullying, and that anyone not maintaining such standards would be investigated with appropriate disciplinary action taken.
