Everyone involved

An Iraqi photojournalist on contract to Reuters, and by 22 already one of the agency's most-used photographers in Baghdad. He was carrying a long telephoto lens when the first burst of 30mm fire was aimed at the group he was standing in.

A Reuters driver and fixer with four children. He survived the first burst, and was crawling at the kerb when a van stopped to pick him up. The second engagement, aimed at that van, killed him.

He was driving his two children through the district when he saw a wounded man at the roadside and stopped. He was killed trying to lift Saeed Chmagh into the van. Both of his children were in the front seat.

Between six and nine other men were killed in the first burst of cannon fire. Most have never been publicly named. At least one of them appears in the footage carrying what the crew identified as a rocket-propelled grenade launcher.

Roughly half an hour after the first burst, the same crew fired three Hellfire missiles into a partly built residential block. The number killed there is disputed and no full list of names has ever been published.

Saleh Matasher Tomal's son and daughter. Both were in the front of the van when it was fired on, and both survived with serious injuries. American soldiers pulled them out and carried them to an armoured vehicle.

The callsign of the AH-64 Apache whose gun camera recorded the footage and whose crew fired in all three engagements. The two men in the cockpit have never been officially named, and this archive does not guess at who they were.

The wingman aircraft. It was working the same area at the same time and its crew appears on the radio throughout the recording, but the video the world saw came from the lead aircraft.

An infantryman with Bravo Company who reached the van minutes after the second engagement, found the two wounded children inside and carried them out. He left the Army and spent years speaking publicly about that morning.

Served in the same company in the same part of Baghdad. He was not at the scene that morning, but in 2010 he and Ethan McCord wrote a joint public apology to the families of the people who were killed.

The infantry company operating in Al-Amin al-Thaniyah that morning. Its soldiers were the ones who arrived after the shooting, found the children, and whose war that year was later written up in detail by an embedded reporter.

An intelligence analyst deployed east of Baghdad who found the video on a military network and sent it, with hundreds of thousands of other files, to WikiLeaks. She was arrested in May 2010 and served seven years.

He ran the organisation that decrypted, edited and published the footage, and presented it himself in Washington in April 2010. Fourteen years of legal fighting followed, ending in a plea deal in 2024.

A former hacker Manning confided in over instant messenger in May 2010. He passed the conversations to the US Army and the FBI, and spent the rest of his life defending that choice.

A Washington Post journalist embedded with the same battalion. His 2009 book described the airstrike and quoted the cockpit radio traffic months before anyone outside the military had seen the video.

Reuters asked for the footage within days of the deaths and kept asking for almost three years through freedom-of-information requests. It never got it. The copy the world saw came from a leak instead.
