Plans to close more military sites throws thousands of jobs into doubt, unions warned.
Another 56 Ministry of Defence sites are to close, including the historic Fort George in Scotland.
The plans are part of the Government's Defence Review that aims to cut thousands of civilian posts under huge budget cuts.
The Public and Commercial Services union said the cuts will severely hit the support available to armed forces and will further damage morale.

The union will oppose closures and job losses, adding that the MoD should learn from previous mistakes if it sells off land for housing.
PCS general secretary Mark Serwotka said: "We are opposed to these closure plans that throw the future into doubt for thousands of staff.
"The MoD has a poor track record on selling off land for homes and this again exposes how the Tories are simply paying lip service to the urgent need to address the housing crisis."

Unite national officer Mike McCartney said: "In many instances the bases earmarked for closure are at the heart of their local communities providing a source of decent and secure employment.
"Their closure will be a severe blow to the local economies where they are located and the people whose livelihoods depend on them.
"Over the coming weeks we will be analysing the detail of the proposed base closures and pressing the MoD to step back from its brutal base closure programme."
