At least I like the mod...
If you ever tried the campagne or fooled around with a troup of the Rainbow Six soldiers, they are really stupid. They shoot just fullautomatic, if you set them to "recon"-behaviour, they see enemy they just start firing and stay then "attacking", so it basicly has no advantage to use "recon"-mode... If you give them room clearing go you can expect that all your team is dead.
Well, this mod really changes it. Just do how it says, activate in mods ingame and enjoy some really good AI.
Improvements are displayed on the link there. Mirror still online.
Really good, and you can really let your mates work now. They kill tangos accurate. Not overpowered, but just not that dumb.
