It is hoped the system will save several millions of pounds over the next 10 years by cutting paperwork and administrative chores by putting 20 HR functions into employees' hands.
The organisation will allow users in locations around the world - including Iraq and Afghanistan - to access the system online using a credit card-style chip-and-pin authentication.
The system, provided by Capgemini UK and Microsoft UK, was tested for 18 months on several MoD units and can now be accessed by any member of staff from a PC, laptop or mobile phone.
David Longhurst, the MoD's project leader for the scheme, said: "We have been modernising our internal administrative processes by changing from paper-based systems to an electronic service. While this has worked well internally, we were left with about 10,000 staff unable to access our internal system online from their place of work. We wanted to give all of them secure access to the appropriate MoD systems from any internet-connected PC."
Online HR self-service access for MoD military and civilian staff around the world
The Ministry of Defence (MoD) will allow 10,000 military and civilian staff around the world to access its self-service HR system to update personal details and book onto training courses.
