It has become fashionable of late in U.S. government circles to undermine the U.S. defense forces. The General Accounting Office (GAO), the Federal Communication Commission (FCC) and the White House (POTUS) have all pitched in, doing their share to weaken the capability and downgrade the tools with which our warfighters enter conflict.
The Russian Defense Ministry has publicized tests of its new Tornado-S precision missile, which takes GLONASS data input for its target and flies in squads capable of taking out dispersed enemy formations. The missile comes in a multiple launch rocket system (MLRS) that can fire up to 12 missiles simultaneously in a coordinated attack.
