The Defence Secretary has commissioned a review into bullying and harassment across the armed forces.
Gavin Williamson announced the decision on Twitter on Friday evening.
The intervention by the Cabinet minister and the military top brass came after The Sun newspaper reported that six Army sports club members had been held over a serious sex attack on a sleeping 17-year-old female soldier.
The teenager is said to have told superiors she woke to find the men - one a staff sergeant - standing over her.
The Defence Secretary was left "horrified" by the claims and has launched a review of behaviour across the military.
"There is no place for this kind of action in the military."
The paper reported Mr Williamson also rang the Chief of the General Staff, General Sir Mark Carleton-Smith to express his displeasure about the incident.
General Sir Carleton-Smith laid down the law to his troops in a video message after six British Army troops were arrested over an alleged attack on a teenage female soldier.
He said inappropriate behaviour is unacceptable and in stark contrast with everything the Army represents.
"[This behaviour] betrays indiscipline wildly at odds with the values and standards that represent the fabric of not just our Army but the nation’s Army," he said.
The review will be led by a senior officer and a civil servant.
The latest scandal comes after the Army faced criticism over a video showing paratroopers using a picture of Jeremy Corbyn for target practice.
The Ministry of Defence launched an investigation into the conduct of the personnel from 3rd Battalion, Parachute Regiment, who were filmed in Kabul, Afghanistan, shooting at a picture of the Labour leader.
