How to view a tree
Step 1: choose a branch (ground, air, or naval) using the buttons below.
Step 2: choose which version of the tree you want to view for that branch
(for example: standard, no subtrees, no paper vehicles).
Once both are selected, the tree will appear further down the page.
Use the “Hide controls” button in the corner to get all buttons out of the way,
and “Show controls” (the small +) to bring them back when you want to switch tree.
Step 2: Choose a tree version
Select a branch above to see available tree versions.
