The ARMA series have dominated the 'First/Third Person Shooter MilSim' genre of games for the last decade or so, beginning with ARMA: Cold War Assault, originally Operation Flashpoint (The name has since been sold of to another company,ruining the title forever). Since then, it has improved to become extremely authentic and realistic, despite the aging graphics and the odd glitch here and there.
If anyone already plays this, or just wants to find out more of this beautiful game, here's some videos from the YewTewb:
