At the end of the nineties the munition for the TOW weapon system in use at The Netherlands army, has to be replaced. The Life of Type of The Tow carrier ends in 2005. The long range anti armour study is to gain insight into the possibilities and limitations for the Netherlands army to deploy future (time period 1995-2000) weapon systems in the long range anti armour battle. The first study results are expected at the end of 1989. The study is sponsored by the Netherlands army and is carried out by the three National Defense Research Organization Laboratories: The Physics and Electronics Laboracory TNO, the Prins Maurits Laboratory TNO and the Institute for Perception TNO. The study considers two categories of candidate weapon systetms namely line of sight and non line of sight weapon systems. The Operations Research effort within this study is mainly focussed on analyzing and comparing the effectiveness of the different weapon systems options. Therefore wargaming, terrain analysis and combat simulation techniques are used. In the paper these techniques will be presented and some results will be shown.
