Dugway Proving Ground
This is a U.S. Army facility that was established in 1942 to test biological and chemical weapons. Located in the middle of the Utah desert, this is the perfect place for playing around with the worst kinds of weapons.
Starting in WWII, fake German and Japanese villages were built here for ordinance testing, and from the 50’s onwards, rigorous testing of Anthrax, nerve agents and the like were done here, and its still going on, despite a global ban on biological and chemical weapons.
It’s also theorized that the increasing popularity of Area 51 has led the government to move all the proof of extraterrestrial activity here.
