Frequently asked
Can serious defence analysis be done with free sources only?
Substantially, yes. Procurement notices, parliamentary answers, open transfer datasets and audit reports are all free and all primary. Paid services mainly add convenience, consolidation and market sizing rather than exclusive access to the record.
