Frequently asked
How do think tanks differ from trade press?
Think tanks analyse doctrine, force structure and policy options on longer cycles. Trade press reports events and contracts on daily cycles. The index separates them because they answer different questions.
Which institutes publish reusable data?
The highest-ranked open-data publishers release machine-readable datasets on military expenditure and arms transfers, which can be cited and reused directly rather than quoted second-hand.
