This whole article reads like classic Russian bombast and self-promotion. Typically, you can disregard almost any claims made in such a piece, because they're almost certainly false.
Something this writer leaves out is that the Russian tech is untested in combat, whereas the PAC-3 is the end result of development lessons learned in combat since 1991.
Russian stuff is untested,but it wouldn't be false to say they have also learned the (harsh) lessons of GW-1 or the Balkans conflicts & integrated that into their new systems.
Ya mean kinda like our own DBM?
Why would Dan Rathers give Hillary control networks Lie?
