A Navy SEAL reassured a teammate dying from multiple gunshot wounds that this portion of his book would be "awesome,” sources confirmed today.

"This is awesome. I'm talking about this on every stop of my book tour. No way I don't hit the bestseller lists after this," Chief Petty Officer Brian Costanza told his fellow SEAL, Petty Officer 3rd Class Chet Steel, who was gasping his last breaths.

As the MEDEVAC helicopter departed with his teammate's corpse, Costanza jotted down plot points and significant details about the incident to use in "Triumph of the Will: A Navy SEAL’s Journey Through Syria."

Costanza said he was thrilled to have a significant emotional hurdle to add to the main character arc in the yet-to-be published memoir, but he faced backlash from some of his surviving teammates for the way he handled the incident.
