Builder says he relies on "common sense" as he fights alongside Kurds against the Islamic State
The rocket launched with a loud bang and the sound reverberated through the air. Tim Locks faced an agonising few seconds’ wait before it reached its target and a cloud of dust and smoke rose from where the building had been.
It was a perfect, direct hit and his comrades let out a huge cheer.
Tim was on the front line in Kurdistan and inside the building had been IS jihadists, also known as Daesh .
But Tim has never been in the army, nor has he had any military training.
He is believed to be the first British civilian without a military background to head to the front line.
Just a few months earlier he had left his comfortable life in Britain to fly to the war-torn region as a volunteer, to fight against IS with a Kurdish militia group.
