Highland MP Drew Hendry insisted last night the battle to save Fort George and Kinloss Barracks was far from over after the Ministry of Defence announced the closure of 13 military sites in England.
The list of facilities being sold off did not name any north of the border.
But further casualties are due to be unveiled later this year and an MoD spokeswoman confirmed that all assets remained on the table.
Those on the latest list are expected to raise £225million as part of a wider defence estates review aimed at delivering £1billion in revenue and providing space for 55,000 homes.
Mr Hendry, who will meet Defence Minister Mark Lancaster next month, told the Press and Journal that the numbers exposed the extent of the risk to the Inverness and Moray bases.
He added: “There are clearly going to be some harder decisions further down the line.
“They are very far from being saved. We were absolutely right to highlight the fact they were under threat.”
SNP Westminster leader – and Moray MP – Angus Robertson added: “These closures are just a fraction of the billion pound target for land disposal that has been set by the MoD.
“With further announcements expected within weeks, we need to re-double our efforts.”
It emerged in June that Fort George, which was built after the Battle of Culloden and has been home to the famous Black Watch battalion since 2007, had been earmarked for closure.
It has also subsequently come to light that the future of Kinloss is being considered as part of the same review.
And fears were heightened last week when Scottish Secretary David Mundell revealed it was “highly likely” some Scottish sites would be “released for disposal”.
An MoD spokeswoman said: “[Our] land currently spans about half a million football pitches. We are looking to sell what we don’t need, so that new homes can be built on it.
“Every penny made will be invested back into defence on things like the new maritime aircraft at Lossiemouth or the new ships being built on the Clyde.”
Last month, The Press and Journal’s petition against closing Fort George, signed by more than 5,000 people, was handed into 10 Downing Street.
