UNSC Tactical Simulator

"We're going to study the historical battles in hopes of increasing your tactical skills for the future. As a bonus, it's a pretty fun game you can play in your spare time."

- AI Roland's introduction to the simulator.

The UNSC Tactical Simulator (TACSIM) is a computer program used for the training of the SPARTAN-IV supersoldiers aboard the.

Usage
Unlike the War Games training in the Infinity ' s advanced combat deck, the Tactical Simulator is a smaller-scale program that functions on data pads. As opposed to having the users engage in direct, fully simulated combat, the TACSIM employs more abstract mechanics, producing either fully hypothetical scenarios or recreations of historical battles with users assuming the role of soldiers who participated in those engagements.

Historical simulations

 * There is a simulation of the Battle of Draetheus V, in which users alternate between the roles of Spartans Edward Davis and Sarah Palmer.
 * There is set of missions is centered around battles for the Forerunner artifact known as the Conduit in New Mombasa in 2552 as well as on Installation 03 and in New Phoenix in 2557, in which users replace the roles of Alpha-Five, a Headhunter, another ODST squad and another Headhunter in their respective missions.

Hypothetical
The simulator also contains a mode designed to train Spartans to combat the Flood should the parasite reappear as a threat.

Production notes
The Tactical Simulator acts as the fictional framing device for Halo: Spartan Assault and Halo: Spartan Strike.
