So this is the famous unit that was training with those puma helicopters : French Police Nationale RAID.
It was really a blast to be able to work with them, even though everything went very fast !
No time for some nice posing here, they were fast roping from the pumas and assaulting an abandoned house to free some hostages.
The challenge for me was to try and stay under the rotors ( thank you ski mask & ear protection !) and then to run with them to the building, a couple of hundreds meters away were the hostages were kept.
