The T64 and T80 is the technological high-point of the Txx line of the cold war era - the T72 is a much more basic (but affordable) tank.
Both the T64 and T80 received laser designated ATGM for accurate fire to 4-5km at a time when 2.5km was considered 'long-range' tank gunnery.
The accuracy of these is still superior to any unguided weapon at these ranges today in good conditions, and the flight time is less than half that of TOW.
