Sons of Struth founder Craig Houston has waded into the bitter row between Rangers and Club 1872.
Sparks flew on Tuesday as Club 1872 aimed a scathing statement towards the Ibrox board before the club responded with a hard-hitting blast of their own.
The simmering tensions continue to build against a backdrop of fan protests over the club's decision to sign up for the Sydney Super Cup, where they will face Celtic in a friendly.
Record Sport revealed last week the club are considering pulling out of the exhibition tournament in the face of anger from punters.
It's served as a catalyst for existing discord between Rangers and Club 1872 to spill over yesterday.
And now Houston, an influential fan figure with the Sons of Struth group during the Rangers boardroom battles of yesteryear, has declared he's "out of retirement".
He's directed his ire at Ibrox head of communications David Graham, who also came under fire from Club 1872, over the tone and language of Rangers' statement on Monday.
Houston wrote on social media: "Now you seem happy to forget those people you went to games with and stood beside supporting your team with, the rank and file. Your words used to describe them as “rump” and use of inverted comas around “supporters” suggests those who don’t toe the part line are not proper supporters.
"Does that mean those ignored by the board and seen simply as a cash cow are now to be considered the enemy of the club because they won’t bow down and accept every decision the club make without the right to question and debate?"
And he continued with the announcement he's ready to get involved in the escalating row.
Houston added: "Your threat yesterday to deal with the disrupters and their propaganda war at the end of the season is laughable.
"I’ve no idea if I am one of the “rump” that you intend to target but I certainly hope I am because I’ve spent near a decade telling the Rangers fans the truth despite being arrested, sued and threatened with my life for doing so.
"That won’t stop me because it doesn’t suit you or your employers agenda.
"I thought I’d retired from campaigning but your threats and insults yesterday have made me change my mind. I’m out of retirement and stand proudly with the rump."
Houston was a key figure in helping drive out the despised regime involving Mike Ashley that preceded the Three Bears - Dave King, Paul Murray and John Gilligan - sweeping to power in 2015.
King's installation as chairman was a turning point in the club's history and the beginning of the end of a tumultuous period as Rangers rose back to the Premiership.
