This picture is something of a classic. It shows 3 American soldier helping a wounded Viet Cong that had an enamel bowl strapped on with rags to hold his intestines in while he kept fighting. If you remember in Apocalypse Now the line by Lieutenant Colonel Bill Kilgore:

"Any man brave enough to fight wit his guts strapped to him can drink from my canteen any day."

It came from this photo. The director of Apocalypse Now was inspired to write that line after seeing this photograph.
