Since Assist is down, the site download went with it, and older versions won't update themselves, because of the lack of a server.
Here is to those new Mac users who don't have a serverlist, or are tired of typing ip's into the console.

ASSIST! A WORKING DOWNLOAD!

All the necessary files needed to play America's Army through the Assist are as follows:

America's Army 2.5(If you already have AA downloaded, you can skip this, but it is needed for Assist)
Two options now-
2.5 Assist(more updated version with buddy list and more cool features)(choose Softpedia mirror)
7za(IMPORTANT!)
OR
2.5 Deploy(older version, lacks many features but takes much less time and computer memory to load severs)

All right. If you decided to use 2.5 Deploy, rather than Assist, skip the first 10 steps

1-Move Assist to your applications folder.
2-Start Assist. Be patient, it lacks a brain.
3-It should now (eventually) give you an error saying it lacks vital components or your internet failed.
4-Little does it know, that is not the case. Quit Assist.
5-Go to your Home folder which should be named after your (Mac)account.
6-Go to your Library folder via your Home Folder.
7-Go to your Application Support folder.
8-Open the 25Assist folder.
9-Delete everything in it, including the 7za file in it(not the one you downloaded).
10-Move your recently downloaded 7za file into the 25Assist folder.
(2.5 Deploy, start here)
11-Start up Assist/Deploy. They will both take some time to load(get used to it).
12-Assist/Deploy will prompt you to copy your current AA installation. If it cannot find it, manually browse and give it the path to it.
13-Once AA has been copied, you're ready to go. Enter your User info, click Deploy, and join a server.

Keep two point five alive!
