Duplicated objects copy animation I have been designing a defense tower. I have a sphere that rotates around 360deg as it's default animation. I added two cylinders to it, one being the base for the guns, and the other being the actual gun. I plan to add another animation to as well. 

The problem is that the gun cylinder(s) "Cylinder.003" are linked somehow. I used &#8679; Shiftd to duplicate the cylinder and I have 2 of the exact same cylinder. When I try to make my animation, both cylinders move, but I only want one to move at a single time. If anyone can tell me how to "unlink" these "linked" objects, it would be much appreciated. I am stuck on this project until I can unlink it.

Any help would be greatly appreciated.
In object mode, select one of the cylinders and press U to bring up the Make Single User menu.  Choose the Object Animation option. Now they will each have their own Action datablock you can animate.
