This film is also a departure in that Rambo doesn’t get his signature firearm or a variant of it, the M60 machine gun. Actually, he really doesn’t use any one gun for very in this film, frequently trading them out for guns he finds along the way. This makes a bit of sense in the context of the film. He makes his way to Afghanistan with the help of the CIA spook who was working with Trautman, so he can’t bring a lot of gear. When he meets his contact, he has some gear waiting for him: C4 explosives and timed detonators, a bow and explosive arrows from the previous film, his knife (presumabley), and some clothes and other gear, but no gun. After all, the plan was to silently get Trautman out and escape the enemy fort with nobody the wiser.
