Leo Varadkar is getting his own personal military aide as he beefs up his role as Tánaiste.
Mr Varadkar is strengthening his presence in the coalition with an Office of the Tánaiste in Government Buildings, allied to his portfolio as Business Minister.
The move will see Taoiseach Michéal Martin and Mr Varadkar operate more akin to the first minister and deputy first minister in Northern Ireland.
In a break with protocol, the Tánaiste will join the Taoiseach and President in having his own aide-de-camp (ADC) - an Army officer who accompanies him to official events.
The move comes at a time when Defence Forces staffing is under intense pressure.
The Fine Gael leader will retain many of the trappings of the Taoiseach's office he surrendered last weekend.
The post was advertised internally this week by the Defence Forces, inviting applications for an "ADC type role with An Tánaiste".
Officers are being told the posting will be for a minimum of two years. The officer selected will be reassigned from their existing duties.
However, the Tánaiste won't be getting an officer at the same high rank as the President, whose ADC is a colonel, or the Taoiseach, who is attended by a commandant.
The Tánaiste's ADC will be an Army captain or Naval service lieutenant.
Mr Varadkar's new office sees the return of a structure in place during the 1990s. Then Tánaiste and Labour Party leader Dick Spring set up a formal Office of the Tánaiste, which gave an enhanced presence to the junior party in Government Buildings. Mr Varadkar will use it to liaise primarily with Fine Gael ministers. It will operate parallel to the Taoiseach's office.
The Tánaiste's spokesman said yesterday: "Under the Partnership Government, the Taoiseach and Tánaiste will both be conducting a number of public roles including State occasions.
"Consequently both the Taoiseach and Tánaiste will retain an ADC in order to fulfil the greater level of representation at public functions and other duties. The role will be filled by an existing officer at no extra expense to taxpayers."
Last Sunday, Mr Varadkar's first official duty as Tánaiste was attending a commemoration for the 1920 India Mutiny, in which the Connaught Rangers mutinied in India in support of Irish independence.
