The name explains it all....You have to kill Osman Atto(Aidid's financial chief).Why:FOR FUN!!You will land at Atto's Outpost by the river via Black hawk and must find and kill him.Atto runs away 2 times which makes this a nice "Cat and mouse chase".But in the ending he meets his doom,he gets killed(not by your hands)but does get killed.I won't tell you how,Watch the ending cut-scene it shows you how Atto meets his doom!! NOTE:PLEASE PUT THE /d COMMAND IN YOUR DFBHD SHORTCUT. Have fun Chase Atto!
