With a specificity of the number of shots and the spatial reconstruction of the scene, there's some impressive uses of tech to bolster reporting:
>A digital reconstruction of the scene shows that the soldiers would have had an uninterrupted view of the arrival of the convoy.
>The reconstruction was jointly achieved with the two survivors of the incident, with an immersive spatial model they could walk through and amend. Together with spatial and audio analysis we established the position of the soldiers on an elevated ground with an unobstructed line of sight to the emergency vehicles.
What digital reconstruction? They took a witness and basically did what they said in a 3D editor. I don't see anything sophisticated about this. They also did things like count weapon sounds in audio, which might be the only factual reliable data point on this report.
Forensic Architecture, the people who did the spatial reconstruction, have been around for a while. You can see more examples of their investigations here: https://forensic-architecture.org/
