Corporal Hughes had been tasked with mentoring the Afghan National Police and was attached to F Company, 2nd Battalion The Royal Gurkha Rifles, when he was injured.
He said:
"The incident occurred whilst I was on foot patrol in Helmand province, on Operation PANTHER'S CLAW. I sustained a gunshot wound to my right flank, entering through my side and exiting through my abdomen/chest.
"Thankfully the round missed everything it could, but I had to undergo an emergency exploratory operation just to make sure it hadn't hit any of my vital organs or caused any internal bleeding."
Currently undergoing rehabilitation, he added:
"I am on the way to making a full recovery, and am in good working order apart from a few scars."
Cpl Hughes, aged 26, from Chaddesden in Derby, joined the RAF in April 2006. He is currently based at RAF Halton in Buckinghamshire, performing general police duties. His first overseas tour was to the Falklands Islands in 2008, before being deployed to Afghanistan in March this year. He was brought back to the UK by an RAF Aeromedical Evacuation Team in July.
On Sunday, Cpl Hughes will be pushing the wheelchair of Dennis Cothay who served as an RAF policeman in the 1950s. Once back to full health, Cpl Hughes's next posting will be to the Tactical Police Wing at RAF Henlow in December.
Cpl Hughes said:
"It was a great honour to be asked by the RAF Police Association to be part of this parade with them, especially after my recent operational experience in Afghanistan."
