We all saw it at once. Half a dozen voices screamed 'Grenade!' simultaneously. Then everything went into slow motion. The grenade took an age to travel through its 20 metre arc.

April 2004: Sgt Dan Mills and his platoon of snipers fly into southern Iraq, part of an infantry battalion sent to win hearts and minds. They were soon fighting for their lives. Back home we were told they were peacekeeping. But there was no peace to keep.
