In version 4.3, VR-Forces introduces the notion of aggregate-level simulation. Okay. What exactly is the difference between aggregate-level simulation (ALS) and entity-level simulation (ELS)?
At the core, aggregate-level simulation is a more abstract level of modeling and therefore is more suitable for representing higher echelons of a force structure " units like companies, battalions, and brigades. Entity-level modeling has the fidelity appropriate for individual entities, like vehicles and human characters.
Lets look at maneuver modeling as an example. In ALS, units have to slow down to move through a forested area, whereas entities in ELS have to maneuver around individual trees. This higher level of abstraction happens for all the types of models. Combat in ELS happens when an entity has line of sight with another entity. When one entity fires, a hit/miss calculation is performed between the detonated ordinance and the nearby entities. Damage is assessed only for the entities that are actually hit. In ALS, units, which cover an area, must have line of sight to the "area’ of the other unit. Combat then proceeds as rates of change in the resources and status of the units. For example, a large, well-equipped unit will more quickly deplete the resources and status of a smaller less equipped unit.
VR-Forces users now have the choice of both simulation levels: entity and aggregate.
