There is an increasing interest in the use of unmanned ground vehicles for defense and security. Collaboration and coordination of these vehicles is very important for survivability. A set of unmanned vehicles in the battlefield have to be controlled by a commander for safety of soldiers in the battlefield. In order to achieve this objective reliability and complexity of these vehicle networks is to be ascertained at various stages of the operations in the battlefield. The objective of this paper is to suggest procedures for ascertaining the reliability and the complexity of unmanned vehicle. In this paper we suggest matrices for reliability and complexity of unmanned networks. A demonstration of the simulation of the suggested procedure would be given. The suggested procedures should be applicable to any number of vehicles in different configurations in the battlefield.
