There you go. I hope the guide helped answer some of your questions about this great game, and helped you get the best performance and image quality out of America's Army on your machine. I sourced most of these tweaks from the Official America's Army Forums and from my time spent researching and writing my Unreal Tournament 2003 Tweak Guide - since America's Army is based on the Unreal game engine.
Anyway, enough tweaking, now it's time to get back into the battlefield and perforate some Opfor. Double time it soldier!!
If you have any comments or suggestions, or tweaks or resources you believe should be inserted in the guide I would love to hear from you. Email me by clicking my name at the top of this guide. And if you see me online, say "hi!" - I play under the nick PersianImmortal and I usually try to be a team player :)
Here are some great sites which contain more helpful information on America's Army such as the latest news on the game, strategy guides, AA community discussions, and useful utilities. I highly recommend you check them out:

Note I've also recently written The Simple Antialiasing and Anisotropic Guide, and on page 5 of that guide I provide image quality and performance comparisons for America's Army using various levels of Antialiasing and Anisotropic Filtering. If you get a chance read the guide for more information.
Check here back often as this entire guide is constantly maintained to have the latest and greatest info on this game!
