Communications and distributed information systems are increasingly vital to the defense community. The fact that OPNET was selected again for NETWARS, this time for up to five years, demonstrates the government's confidence in us. We believe that OPNET technology and expertise are broadly applicable to the defense market, a market in which we intend to expand our presence."
