Zipper5 has released an Anti-tank Launcher vs. Infantry Fix addon on the BI-Forums.
The AI since ArmA has always been inclined to use their rocket launchers at range rather than their rifles. Many fixes for this were made for ArmA, but none have been made, to my knowledge, for Arma 2. Therefore, I decided to make this simple addon. I saw a lot of people harping on about it in the OA thread, so hopefully this can put the whining to rest.
