How does Mark Bowden use imagery in Black Hawk Down: A Story of Modern War?

Examples of Imagery:

"He really did go cyclic on the .50 cal then, just fired continually for maybe as long as a minute, taking down trees and walls and anyone in, around, or behind them, before Sergeant Lorenzo Ruiz stood up in the turret and took the gun."
The Assault, p. 63

"But they had seen it, the chopper spinning, falling, one of the D-boys hanging on with one hand, both feet in the air, riding it down."
Black Hawk Down, p. 80
