Eagle

Eagle is a high-level constructive model that addresses and assesses force-level requirements at the division and corps levels. Essentially a mathematical model, it provides gross requirement determinations based on the execution of a battle scenario involving up to a two-division corps against semiautomated forces in a combined and/or joint air-land battle. It incorporates logistics requirements based on expected rates of consumption.

Vector-in-Command

Vector-in-command is a constructive model that can be run at the battalion task force to division and corps levels, depending on scenario construction. It is used extensively within TRADOC to assess the performance effectiveness of proposed new weapon systems, conduct assessments of new doctrine, and address the potential impacts of organizational or procedural changes. The model is stochastic and operates according to sets of rules programmed for the scenarios planned for the assessment.

Extended Air Defense Simulation

The extended air defense simulation (EADSIM) is a system-level analysis simulation capable of assessing the effectiveness of theater missile defense and air defense systems against a broad range of extended air defense threats. The model incorporates fixed- and rotary-wing aircraft, ballistic missiles, cruise missiles, radar and infrared sensors, satellites, command and control structures, electronic warfare effects, and fire support. It is a time- and event-stepped two-side reactive model that executes a planned scenario. In its basic configuration it does not operate as a human-in-the-loop simulation. Used primarily by the U.S. Army Space and Strategic Defense Command, it can be confederated with other theater- or campaign-level constructive models, as well as some system virtual simulators.

Corps Battle Simulation

Currently, corps battle simulation (CBS) is the primary simulation used by the Army to train staff officers at the Army's Command and General Staff College at Fort Leavenworth, Kansas. It is employed to support a number of higher-level division and corps exercise programs and has been used extensively to support assessment of the Army's advanced warfighting experiments. CBS is a constructive simulation originally designed to be conducted at the division level, and subsequently revised and expanded for use at the corps level. It interfaces with other models and simulations, such as air warfare simulation (AWSIM), tactical simulation model (TACSIM), combat service support training support
