New body cam footage is revealing New Orleans cops putting themselves in incredible danger to stop the Bourbon Street terrorist attack.

The newly released video starts after the suspect, Shamsud-Din Jabbar, had mowed down NYE revelers and crashed his truck ... and you see officers swarming around the vehicle with their guns drawn.

With the driver's side door open, one officer was closing in, just inches from Jabbar, who the cops couldn't see due to the airbags deploying in his truck. But, without warning, the terrorist came out firing his gun from behind the airbag.

The officers quickly retreated, but returned fire as they did, and killed Jabbar.

As we reported, 2 NOPD officers got shot during the exchange and were hospitalized, but they survived the injuries.

While there was criticism of how Jabbar was able to get around police barriers to make it onto Bourbon Street and mow down 14 people -- the heroism of the officers who took him down is on full display in this new video.
