Upon leaving the Special Forces, Ollie worked in Iraq as a private security contractor before heading to South-East Asia, using his incredible military training to benefit the lives of those less fortunate. While working for a charity, he was lead command of a three-man team bravely infiltrating child trafficking rings, rescuing children and bringing them to safe houses.
