Why read this explainer

Begin with the different endings before comparing the confrontation's meaning. The film leaves Rambo alive and ends on his breakdown, giving trauma and mistreatment more emphasis than mutual destruction.

PlotGeeks note

The novel treats Rambo and Teasle as mutually destructive, while the film emphasizes trauma and mistreatment. Preserving Rambo's life makes his breakdown the ending's decisive response to that conflict.
