well I can tell you this, I seen a laser knock down a jet at super sonic speed in white sands in 87, I also seen other stuff that will boggle the mind, AD s the most advanced part of our military, we have Himad figured out now we are worried about swarm with drones, tech that we also pioneered so focus is shifting back to shorad, funny enough the weapon systems I started on and are now in museums are now getting refurbed and bolt on electronics that will boggle the mind. I worked on the development team for the US Army version of ADATS for two years, we couldn't get the system small enough for reliable deployment on a bradley chassis, but that system was undefeatable. You have to imagine pretty hard to understand what they are working on right now. An old engineer from martin marietta, a ww2 camp survivor from lithuania, told me our rule is to work two generations ahead of the next possibility, that comes from DARPA. Whatever that shithole Russia has we are 3 generations ahead of it and we have already developed a countermeasure to what we have so I don't worry about them. I have been in 10 shoot downs of jet and rotor aircraft. you can see many on youtube now.
