I wondered about that as well. The other purchases may/could be explained...the DHS of 1 billion is alarming.
I wouldn’t know where to search- but I would be very interested to know if these types of purchase are common and have always been- or have they been made in this quantity since 9/11...or..just in the last 3-4 years..
What I’d really like to see are the tactical plans of dealing with “civil unrest”..
Tactics aren't where you need to be concerned: wars are won with logistics.
