Mike has revealed all of the Army requirements already. However, due to SA-MP issues, Mike removed it (https://mikescnr.com/forum/index.php/topic,509.0.html). But there is a way to add the Army again.
Players constantly record themselves. So, having this requirement (recording your actions always) can bring the Army back to the game. And because the Army is overpowered, only players who can video (or record) themselves constantly should be able to apply for it.
When needed, staff can ask for videos to review our actions if player A reports player B.
Remember that players already record themselves constantly. So, the Army should be back with this requirement.
