Women in the army who are unable to lock their doors are moved to hotels for their safety, can reveal the mail.
Top brass checking locks and espionage contracts are mounted as standard on female single rooms in army, naval and RAF barracks.
And every woman without access to lockable accommodation will be housed off-base.
The drastic measures that reflect the severity of the threat to female staff are supported by the Network of the Army Servicewomen. It is assumed that the abuse of serving women is taken.
The e -mail discovered the policy after an investigation last month into the death of Teenage Gunner Jaysley Beck. She took her own life in Larkhill Camp in Wiltshire after being ruthlessly harassed and sexually abused by male colleagues.
Gunner Beck had to sleep in her car because she could not protect herself while she served in the royal artillery.
Last night, former Tory Member of Parliament Sarah Aherton, who campaigned for the armed forces to improve its welfare provisions to women, said,: “It is disturbing that such measures are required and that so much more must be done to improve the behavior.
'Boy-up male soldiers who are looking for women in their accommodation blocks is known as the' Two O'clock Knock '. It is a known problem in the army.

“It is therefore necessary that the Ministry of Defense takes it seriously.” The last direction on Secure Rooms was signed by the director Basing and Infrastructure of the Army, Major General Richard Clements, and will also apply to women in the Royal Navy and Raf.
An official source said: “This is a repetition of the accommodation policy of the standing forces, rather than a sudden change.
'Defense Minimum Standard is a lockable door. If it breaks 48 hours, it is the maximum time it is allowed.
'If it cannot be solved, the service person, male or female, must be placed in another room. Only if that cannot be done is hotel accommodation booked. '
Several reports have indicated that women in the armed forces are abandoned by abuse and sexual violence.
They have found an urgent need to revise the misogynistic culture of the army and to support women who often feel betrayed by the response of the command structure to their experiences.
The e -mail previously reported the abuse of female soil staff by Raf Red Pilots and Women on submarines.
Last year, a Navy research concluded that women in the submarine service 'misogyny, bullying and other unacceptable behavior'.
And two pilots with red arrows were fired by the RAF for their abuse of female colleagues, while predatory behavior was found 'widespread and normalized' about the display -squadron.
The Ministry of Defense was approached for comment.
