The canine and his handler sergeant Joshua T Rose, are one
of 200 canine action teams deployed by the US in Iraq.
Handler and dog partnerships are so strong that many soldiers
have asked to be buried next to their animals if both are
killed in action.
When sergeant Rose is on patrol with Iron, he takes with
him a copy of an ode to military dogs, which reads: "Trust
in me, my friend, for I am your comrade… I will protect
you with my last breath… when all others have left
you and the loneliness of the night closes in, I will be
at your side."
The Americans have used dogs in military conflicts since
WWII with 4,300 being deployed in Vietnam between 1965 and
1973.
