This bonus selection from the bonus disc in the Rambo trilogy DVD box set in fun to watch as a montage of Rambo using different weapons throughout the three films is shown. Whenever he uses a new weapon, a screen pops up with technical specs of that weapon. Unfortunately, many of the technical specs are wrong. When the specs come up for the knife from First Blood: Part II, the green outline is that of the knife from Rambo III. The montage shows Rambo using an M-60 machine gun in First Blood and the machine gun from the helicopter in Part II. They put both guns under the heading of M-60 but the gun from Part II is a Russian variation on the M-60 concept but is not actually an M-60.
