The Union Bears have demanded Rangers sacked head coach Russell Martin and chief executive Patrick Stewart.
The group has released a lengthy statement insisting they stand with the wider supporter base in calling for change after a dismal start to the 2025/26 campaign.
Hearts stormed nine points clear of Rangers in the Scottish Premiership on Saturday with a 2-0 victory at Ibrox.
This seems to have been the final straw for fans, as if the draws against Motherwell, Dundee, St Mirren and Celtic weren't enough, coupled with the humiliating Champions League play-off defeat against Club Brugge.
The Union Bears have also taken aim at Stewart, and are adamant he must carry the can for hiring Martin back in June, as they called on Andrew Cavenagh and Paraag Marathe to take swift action.
If they don't, the ultras group say pre-planned protest action will occur.
The statement reads: "The Union Bears stand with fellow fan groups and the wider support in demanding the immediate removal of the Rangers management team and CEO.
"Russell Martin has shown beyond doubt that he is not capable of leading Rangers Football Club. The performances under his management are a disgrace to the standards this club was built on. Rangers cannot afford constant upheaval, but in Martin's case there can be no debate. His failure is absolute, and he must be removed from his duties immediately.

"Patrick Stewart has been quick to criticise supporters, yet has refused to take responsibility for his own catastrophic decision. As CEO, the appointment of Russell Martin lies entirely with him. The failure proves he is unfit to lead Rangers. His position is untenable, and he must be held accountable.
"The new owners must act quickly and decisively. If they do not, they will leave the support with no option but to act. Rangers must have a management team and a squad capable of delivering success worthy of our history and our support.
"A series of protest actions have already been planned, beginning with Saturday's match. Unless changes are made before then, these actions will be made known to the wide support."
