No, the idea is to keep it fairly simple. The important thing is that you don't want to exclude anyone. So the idea is that the general insignia are there for the highest level you can go. You might want to go down to a service, say something like the Royal Canadian Armoured Corps, but doing that would easily add another 12, and it would overwhelm the room. I think that by keeping it very simple at key locations, people will be able to identify them fairly easily.
