Combat Sample Generator Model - COSAGE

U.S. Army Concepts Analysis Agency; Bethesda, MD

The COSAGE model was developed as a successor to the individual, stand-alone models of the AMMORATES methodology. The older models made it difficult if not impossible to simulate the interactions that occur between armor, infantry, and artillery in combat. This desire to simulate the interaction was coupled to two other major factors - the large amount of time required for analysts to interact with the data, and the manual preparation of data that could be computer generated.

The model is a two-sided, stochastic simulation model of combat between two forces. Typically, the Blue side is sized as a division and the Red side is scaled from a fraction of a division to a combined-arms army. The model simulates 24 hours of combat and produces expenditures of ammunition by round type and losses of personnel and equipment. Resolution is typically to Blue platoons and Red companies. In some cases such as close combat, resolution is to the individual equipment level.

The model simulates conventional combat between the ground forces and includes both direct and indirect fire weapons, helicopters, mine fields, close air support and air defense, smoke, illumination, and limited visibility.

The results of the model are used to drive the Wartime Requirements for Ammunition, Materiel and Personnel (WARRAMP) methodology. This methodology supports the U.S. Army Planning Programming Budgeting System.
