You miss the point. It would at least fix one of the many things that need fixing. That doesn't mean that all the other bits won't still need fixing.So lets posit the Army buys 200 shiny upgraded CR2's, then what?
Its air defence capability is pitiful.
Its artillery is obsolete and all but non existent.
UAV's are still regarded by too much of Land as a novel fad that will pass.
Its electronic warfare capability is still in the Land of Powerpoint.
Find - Fix - Strike
It can't find, it can't fix, and it can't strike
