"I flew 119 missions in Borneo. Our planes were dropping supplies to Kiwi soldiers and Gurkhas on the border," he said.
That was from 1965-67 and after that conflict ended his squadron was sent to Vietnam.
"We were operating in Malaya between times doing drops there as well, but in Vietnam we were flying supplies to the Kiwi medical staff manning the hospital in Qui Nhon province."
Jock celebrates his 80th birthday in a couple of months, and recalls Anzac Day services when the participants were mainly returned veterans like him.
Nowadays he is "thrilled" to see so many young people turning out every year.
"It's great seeing the kids and families here ..."
Jock's voice trails away, emotion stopping his words.
He may not have marched yesterday, but he was there for his mates who couldn't be.
