// Each entity in a given DIS simulation application shall be given an entity identifier number unique to all  other entities in that application. This identifier number is valid for the duration of the exercise; however,  entity identifier numbers may be reused when all possible numbers have been exhausted. No entity shall  have an entity identifier number of NO_ENTITY, ALL_ENTITIES, or RQST_ASSIGN_ID. The entity iden-  tifier number need not be registered or retained for future exercises. The entity identifier number shall be  specified by a 16-bit unsigned integer.  An entity identifier number equal to zero with valid site and application identification shall address a  simulation application. An entity identifier number equal to ALL_ENTITIES shall mean all entities within  the specified site and application. An entity identifier number equal to RQST_ASSIGN_ID allows the  receiver of the create entity to define the entity identifier number of the new entity.
