Six members of the Army have been sacked over a scandal involving the distribution of explicit emails that denigrate women.

The Chief of Army David Morrison has released a statement saying the men range in rank from Sergeant to Major and are from both Regular and Reserve units.

Three of the members have been the subject of a New South Wales police investigation but it is unclear whether any charges have been laid.

In June, Lieutenant General Morrison revealed Defence was investigating the distribution of hundreds of inappropriate emails and suggested more than 90 personnel may have been involved.

He says four have faced administrative disciplinary action while Defence is considering the futures of several others.

More to come.
