Athena - An Arma 2nd Screen Application

At it's most basic, Athena is an application that you can run on your 2nd screen that provides a very highly accurate representation of the in-game map and displays icons for friendly units in real time: a 'blufor' tracker that runs outside of arma on a 2nd screen whether that screen is literally a 2nd monitor, a laptop, a Windows tablet or a Microsoft Surface but that's an oversimplification of what Athena offers.
