Have this installed and absolutely love it. I play as the CSA and formed an "elite" army consisting the Irish Brigade, Hoods Texans, the Stonewall Brigade, the Orphan Brigade, and Gregg's Brigade. Blows away any Union army I face.
I have had CTD issues with this mod though unfortunately. However, I highly recommend everyone download it.
Also, that guy's tactics in the video are laughable. He just deploys one huge long battle line of 1 rank!
