In this paper we investigate the survivability of multi-level ad-hoc groups for critical operations through a case study. We aim to provide a formal trust framework for establishing security policies. We identify various issues in group formation and evolution. We define components and rules of direct trust and trust recommendation. We then apply them in constructing functioning groups. We also propose some policy guidelines for addressing these issues.
