Back in the early 90s I remember getting a video from the video shop about a squad who drove this gray truck that split in two but had tracks instead of wheels. They were in some were that looked prehistoric with dinosaurs etc. can't remember much of what happened but I remember one scene were they had to drive over a steap hill but couldn't get up so they split the truck and towed each other up.

a.k.a. Born Free (kyoryu tankentai Born Free)


The passage of the Arvy comet close to the Earth generates earthquakes that bring the dinosaurs back to life, who have been hibernating. However the Earth of 1996 is not a suitiable climate. Due to the lack of food, the great reptiles are again threatened with extiction. The born free patrol is formed to transport the dinosaurs to a more suitable ecosystem and protect them from King Buttler the poacher
