ProSIM Company  /  Leavenworth, Kansas  /  Since 1998

The most realistic tactical simulations available.

We build high-fidelity simulations of modern land warfare. Realistic does not have to mean slow and unplayable, and a playable wargame does not have to be shallow. Every title we make is meant to challenge you intellectually, not just mechanically.

Professional pedigree Versions of these simulations have been used as training tools by military organisations around the world, and adapted under contract for Boeing and Lockheed Martin.
Command real time You issue orders and standing procedures down a chain of command. Subordinates execute them. You command, you do not micromanage.
Seven titles From the Falklands and the Golan Heights to Korea and Afghanistan, all published by Shrapnel Games.

The catalogue

Seven titles, newest first. Every one is available as a download from our publisher, Shrapnel Games, who set and publish current pricing.

02  /  Defense applications

Built to train, not only to entertain

The same engine that drives our commercial titles has been delivered as custom scenario packages and analysis tools for defense customers. In 2007 Boeing commissioned a custom build of Air Assault Task Force for ground combat training, paired with their intelligent tutoring and after-action review system.

Counterinsurgency training packs, tailored orders of battle, instrumented after-action data and bespoke terrain are all things we have built to contract. If you are looking at simulation for institutional training, that is a conversation worth having.

03  /  Who builds these

Written by someone who did the job

ProSIM was founded in 1998 by Pat Proctor, then a serving US Army officer. He commissioned out of Purdue in 1994 and retired a colonel in 2019, with service that included the Joint Strategic Assessment Team assembled by General David Petraeus and Ambassador Ryan Crocker to shape post-surge strategy in Iraq.

That is the reason these simulations model command the way they do. The chain of command, the delay between a decision and its execution, the friction of a plan meeting terrain — those are not design flourishes. They are the job.

Rebuilding. prosimco.com is being brought back online after a long absence. The games, the demos and the patch archive are all here again — the multiplayer Arena is still being restored. Get in touch if you need something that is not up yet.
