American Sniper is based on the
memoirs of Navy SEAL Chris Kyle, Scott McEwen and written by Jim
DeFelice. Navy SEAL Chris Kyle is the deadliest shooter of all time,
and is called by his enemies as "the devil." From 1999 to
2009 he set a record with the most murders as a sniper in the history
of the US Army. Kyle learned the tricks of the trade already when he
was a child and would play a prominent role in the fight against
terrorism that began after 9/11.
