Major General Christopher Ghika, Deputy Commander of the Global Coalition’s Combined Joint Task Force, told Forces News: "This is an organisation which set its stall in 2014 in holding physical terrain, today they hold nothing and therefore it’s a significant moment.
"It isn’t the end of the group or the campaign because IS still present a threat to Iraq, Syria, the region and the world, and that’s why the global coalition will continue its operations," he said.
Air Commodore Roddy Dennis, the commander of the UK air component said at the time:
"We're targetting that hardcore element that's left.
"What we see ourselves now is in that final stage of removing those hardened fighters that have sought solace somewhere down in the southern eastern part of Syria and we're having really good success at closing that out.
"I'm very confident that we will see the ultimate demise of Daesh in the southeastern part of Syria, but it will take some time to do that."
RAF Tornado GR4: A Key Component
One of the RAF aircraft that played a key role in Shader until its retirement last month was the Tornado GR4.
Involved from the very start of the operation, they have gathered intelligence and launched hundreds of airstrikes against IS.
Squadron Leader Colin Bolstrom was a Tornado weapons systems operator who completed several Shader tours.
