Professional body builder turned Hollywood icon turned politician Arnold Schwarzenegger visits Jay Leno on Thursday's episode of CNBC's "Jay Leno's Garage," and he brings his 50-ton tank. This 1951 M-47 Patton, equipped with an 810-horsepower Chrysler V12 twin turbo gas engine, is the very same tank Schwarzenegger drove when he served a compulsory year in the Austrian National Army in 1965. He paid $20,000 to ship it to the U.S. in 1991, he explains, but otherwise it was free. Now he uses it to incentivize disadvantaged students to stay in school.

"I bring kids out here from the after-school programs," he tells Leno. "When they stay in school their reward is to come out here and drive tanks with me." "And the ones who don't stay in school — you crush them?" Leno jokes. This isn't the first time Schwarzenegger has managed to merge his passions for educating youth and heavy artillery. In 2014, he worked with the charity-organizing site Omaze to raise money for the After-School All-Stars program by offering a lucky raffle-winner the chance to "blow s--- up" with him.
