Are you sure they have “tanks” as you put it? You’ve seen them? And if they do possess “tanks” the DoD doesn’t want you re-selling surplus military equipment to the general public, so that’s really not an option. There wasn’t a day in the past where Lord Obama bought dashcams for every law enforcement agency in America. That’s not how it works, at least not yet.
Yes, they have tanks. Last time I was there, they booted my Abrahms.
