suggestion for new UI

[oho]

One nice thing in the Take command games (american civil war) is the movement to subordinate units with the arrow down key - to the next unit on the same level with -> to the previous unit on the same level (for example regiment in a corps) with <-  and to the supirior unit with arrow up. So one can navigate on the 3D battlefield while in F5 mode very nicely.
Perhaps its possible to implement this (perhaps with ctrl + arrows because arrows are already used for view movement.

A short comment.
In the present system, 3D view (F3).
Put the cursor on one icon presenting the HQ, Corps, Units before Clicking Right.
The point of view moves to the unit in 3D... and keep the right button... move the cursor on the other icons.
The point of View moves to each entity... Very easy to see all point of view.

Another mode : in 3D subjective view (F5,F6)...
With the up/down page , you can move the point of view on each entity.

Did you use these features? 

That said, I'll take a look at your idea about the hierarchical level.
