For the past five years, London-based photographer Jo Metson Scott has been travelling back and forth to America, photographing and speaking with US marines who spoke out against the invasion of Iraq. The resulting project The Grey Line combines photographs and words in an attempt to examine the personal struggles of men and women grappling with doubt on the frontlines of the “War on Terror”.

Below are some exclusive previews taken from Jo’s scrapbook, where she’s documented the journeys, stories and testimonies of men and women who spoke out about their doubts at varying consequences.

The Grey Line will be published and exhibited in 2013 to coincide with the anniversary of the invasion of Iraq a decade ago.
