The Ministry of Defence has refused to rule out axing the home of The Black Watch.
The Courier revealed on Thursday that Fort George, near Inverness, is being considered for closure.
That sparked fears within the Scottish Government that such a move could lead to the number of those wearing the famous Red Hackle being slashed to around 200, with battalion status reduced to that of a special detachment.
But a source close to The Black Watch said: “Whoever is starting the rumour about reducing them in numbers, it shows a lack of military understanding. The Government has not said anything about a another defence review.”
An MoD spokesman, however, would not guarantee the future of their home.
He said: “As part of an ongoing review, we are aiming to create a smaller and better defence estate that effectively supports our armed forces in the important role they play.
“The MoD is considering how it might achieve this and no final decision about the future of Fort George has been made at this time.”
Options are being considered across the entire defence estate.
A series of announcements have already been made, with the final estate rationalisation plan expected to be announced in the autumn.
It is thought that will contribute significantly towards a £1 billion target for land sales, as set out in the 2015 spending review, and generate significant receipts which the MoD says will be reinvested into better military capability.
SNP MP Drew Hendry called the threat to Fort George “shocking”.
He said: “There can be no good reason for this successful base with its proud military record, both modern and ancient, should be considered expendable.
“It also raises questions about the future of The Black Watch and the risks for downgrading of their current status.
“I would imagine that people will be rightly concerned and angry, but a swift about-turn to reassure local people, the soldiers and their families would be the very, very least that our communities should expect from the UK Government.
“I will be seeking an urgent meeting to rule out this reckless suggestion from the MoD that once again treats the people of this area with contempt.”
A spokesman for Scottish Tory leader Ruth Davidson said: “Ruth is passionate about The Black Watch, and has demonstrated that on a number of occasions.
“She is committed to continuing to speak up for its best interests in the future.”
