In the Star Wars movie "A New Hope", there were some small creatures called Jawas in the planet Tatooine. They were using a big vehicle to put captured droids & other stuff. What is this vehicle's name, and is it bullet-proof?
It's called a Sandcrawler.
From the starwars.wikia article:
Sandcrawlers were huge mobile fortresses which could be seen on the deserts of Tatooine, used by the Jawas as their transport and shelter. They were equipped with a magnetic suction tube for sucking droids and scrap into the cargo hold. They were equipped with cargo holds, scrap processing facilities and quarters for crew and passengers.1 They were large enough to fit an entire Jawa clan.
Although it is not named on screen, the vehicle is explicitly called a "Sandcrawler" multiple times in the script of A New Hope:
EXT. TATOOINE - ROCK CANYON - SANDCRAWLER - SUNSET The eight Jawas carry Artoo out of the canyon to a huge tank- like vehicle the size of a four-story house. They weld a small disk on the side of Artoo and then put him under a large tube on the side of the vehicle and the little robot is sucked into the giant machine. [...] INT. SANDCRAWLER - HOLD AREA It is dim inside the hold area of the Sandcrawler. Artoo switches on a small floodlight on his forehead and stumbles around the scrap heap.
Star Wars has a history of giving names to things in scripts, but not saying them on screen. For instance, the glowing thing held up in the parade at the end of The Phantom Menace is named the "Globe of Peace" in the script, but not identidied on screen. Also, some names appear only in the script and credits, such as the name "Ewoks" only appears in the script and credits for Return of the Jedi, but are not said on screen.
