Australian author Tony Park has seen the impact of war on soldiers first hand.
Major Park, who serves in the Army Reserve and is an Afghanistan veteran, served as a public relations officer for the Australian Army in a bombed-out former Russian aircraft hangar at Bagram Air Base.
He said he witnessed Post Traumatic Stress Disorder (PTSD) among soldiers at the base.
"This is Australia's longest war. We had guys having multiple deployments, sometimes three or four, and you could see this was wearing down people," Major Park said.
"When they went back for their second and their third [deployments], those same experiences became magnified and it was almost like the highs of combat got higher, but the lows got lower as they came back."
RG) I can highly recomend writing especially poetry for a tool in coping with PTSD
