Randomize objects inside an array?

You can use face instancing (aka dupliverts from 2.79): https://docs.blender.org/manual/en/latest/scene_layout/object/properties/instancing/faces.html Note what it’s different thing from collection instances. Create object with bunch of faces and rotate them randomly, then parent object what you need to array to it and change instancing (it’s in object properties) from none to face (note option to hide instancer - it will hide faces): [%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D…

seems relevant. Or just separate the objects of an Array modifier(after you apply?) and randomly move all keyframes of some objects (in this case objects=animated cannons).
I am not sure about the result though.
