Itweas has released his Wolf addon. It comes with a demo mission. I haven't tried it myself but people seem to be impressed, particularly with the animation and scripting.http://ofp.gamepark.cz/index.php?sekce=news
*note - at time of this post the above link goes to the front page news which features the addon. As such, in a couple of days / weeks it may not be there so just search the OFP.info site for the addon.
