Super cool equipment: Tanks openly sold on Amazon!

I'm convinced of Americans. This tank, which is like from a science fiction movie, is sold on Amazon at an ultra-high price of $ 19,999.95. Such things can be publicly auctioned in online stores, and it is worthy of the United States, which is known as the freest country in the world. It is said that it took one to two months to complete this big guy. Selling at such a price is reasonable.
