BARNSTAPLE PC Chris Friendship was at the riot training in Cornwall last week.
He said while people in North Devon might think police in the area do not need to be trained for such events, officers were sent all over the country to cover for their colleagues.
He said: "Trying to train for this is not the easiest thing in the world to do.
"We went to Northern Ireland for the G8 and the July 8 protests.
"At the end of the day everybody has to be trained to the same standard, and if a wheel fell off somewhere we have the ability as a unit to go and help.
"At some point in the future you may need it in North Devon, at which point you'd be relying on other people."
Chris said the riot demonstration in the training teaches officers how to deal with real-life riots.
"I've never faced it in real life but it's something you hear about and you do get the sensation," he said.
And talking about petrol bombs, he said: "If you spend too much time in clothing that's alight and don't get it off it will burn you. These are flame retardant so you've got to learn not to be scared and freak out and say 'oh I'm on fire'. You've got to deal with it."
