1) Introduction
===============
>From Wikipedia:
"America's Army (also known as AA or Army Game Project) is a tactical
multiplayer first-person shooter owned by the United States Government
and released as a global public relations initiative to help with U.S.
Army recruitment."

2) Bug
======
The AA server can be terminated remotely through a specific single
spoofable UDP packet which leads to a failed assertion:
"Assertion failed: VoiceIndex<VOICE_MAX_CHATTERS"
Note: this bug is the same I found and disclosed in Unreal Tournament
2004 some days ago and which affects some other games too (ut2004null).
