I was wondering how to potentially add graphics/images of patches for units. For instance, a Police Dept would have their patch as their image for unit movement, and other Police or Sherriff Units would have their respective patches. I do not need to have animation if responding or not, just being able to see what departments are responding to what calls. I would want the icons to be very very small; as I see different graphics have no scalability or are way too large when looking at an area view rather than on zoomed-in view.
How can this be accomplished?
