About the Guide

This Supreme Commander FAQ is not focused on the storyline or flavorful aspects of the game, but on the technical and data-driven aspects. It’s a reference for those of us who want to know what’s happening under the hood of the game, how to tweak the last ounce of usefulness out of our units, how to beat that unsolvable campaign two different ways.


Throughout this guide, “Commander” and “ACU” are used interchangeably, as are “Subcommander” and “SCU”. Anti-air is sometimes abbreviated to “AA”. Resource costs are usually put in terms of M, E, T: Mass, Energy, Time to build. Each unit of time (T) is 1 second for a unit with build speed 1. For example, the Commander has build speed 10, so he can build a unit with cost T300 in 300/10 = 30 seconds, and if its mass cost is M60, he uses 2 mass/sec.

XBOX Version

This guide does not cover the Xbox 360 version of Supreme Commander. While there are a lot of core similarities in terms of factions, missions, units and their stats, and so forth, there are a lot of glaring differences when it comes to controls used and the overall gameplay presented. The original guide was written for the PC version exclusively and there are currently no plans to add Xbox specific info.
