|I would say know, because even without smart munitions with accurarte MET data a 155mm arty shell will land within 50m of where it is intented and with a 50m kill radious that is good enough. In addition it is much more flexiable. ie it takes much longer for a warplane to target the same target. The one exception is fast moving armoured warfare, the SP arty and even the MLRS can't provide contionous fire support. I don't see arty going away for a long long time. It still is the greatest killer on a battlefield.
