Synopsis:
Sgt. Rock and Easy Company are chased up a hill by two enemy tanks. Rock tells the others that prehistoric cavemen had similar problems. They were chased by mastodons who were impervious to the primitive weapons. However, the cavemen could start an avalanche which would bury the elephants. Rock and Easy do the same to the tanks.

Easy is then attacked by an airplane. Rock compares the attack to a pterodactyl attack on prehistoric men. The cavemen used bait to lure the flying lizard into a trap. Rock and Easy use an empty uniform to draw the plane's fire and destroy it.

Finally Easy Company is faces with a battle against enemy infantry which outnumbers them. Rock tells them to stand and fight like cavemen against a tyrannosaurus. Although Easy suffers casualties, they prevail.
