There is always more to what meets the eye to a weapons contract. Every release, or announcement of every piece of gear, from Vest, to Kevlar protection products, to aircraft. Every time something revolutionary is developed, Somewhere else, sooner or later, something is thought up to counter that threat, through tactics, hardware, or training, sometimes perhaps all three.
Its a race, to make all threats or hardware, obsolete. No matter how astonishing something may seem, there is all ways something to answer, and if you cant , then fight fire with fire. Thats how we get notions like Nuclear war, and fast attack submarines.
