The world of military contractors is far and wide, and way deeper than you think. There are companies that you likely interact with on a daily basis that have been, or continue to be, part of the military industrial complex that you'd never guess would be part of that system. GE helped build nukes. Dell supplies computers and more. Bose doesn't just make stereos; they also make headsets for the U.S. military.
But the one you're most likely to see or have is General Motors.
GM has been a government contractor for decades, having spun off its defense subsidiary in 1950. It's supplied everything and anything, including the legendary Humvee, the Stryker armored convoy, the prior chase vehicles for the U-2 Dragon spy plane, and its latest project, the ISV-U, a Colorado ZR2-based UTV-ified truck. That ISV-U is also why I'm writing today, as while normally, you or I wouldn't be able to buy one until it's well-past its prime twenty years from now, there's a brand new one that could end up in our garages.
