What The Library Does

This page converts the book appendices into a web-friendly orientation layer. It does not try to become a live database of every URL. Instead, it groups the source families that should be checked before any public update.

  • UK strategy and national security: Strategic Defence Review, National Security Strategy, Defence Industrial Strategy, resilience guidance, risk surveys, service personnel statistics.
  • Recruitment and public service: armed-forces careers, police recruitment, nationality rules, cyber direct entry, recruitment reforms.
  • Defence innovation and funding: UKDI, DASA, NATO DIANA, NSSIF, defence-tech investment and procurement routes.
  • Europe and Ukraine: EU readiness, ReArm Europe, Niinisto-style preparedness, Diia, Brave1, drones, Ukrainian wartime GovTech.
  • Human capital and legal: prison coding, TechVets, FIRS guidance, boundary and eligibility sources.
02

Glossary Core

  • Whole-of-society resilience: the doctrine that society, not only armed forces, is part of the security system.
  • Deterrence / Porcupine Principle: making aggression unattractive by making the target costly to frighten, divide, or disable.
  • Dual-use: technology with civilian and defence applications; moral weight sits in use, customer, governance, and oversight.
  • The four layers: shield, nervous system, bloodstream, social fabric.
  • UKDI, DASA, NATO DIANA, NSSIF: funding and innovation doors that should be checked on official pages before action.

Boundary And Safety

The boundary note is essential: defence.is is public-source civic education and research synthesis. It is not operational advice, tactical guidance, weapons instruction, evasion guidance, or adversarial tradecraft.

Eligibility, legal duties, clearance, funding, and service rules change and are decided by the relevant authority. The site can orient readers, but it must keep pointing them back to official pages for decisions.

04

Living Links Model

The living-links model should track route categories rather than pretend the book can stay current: innovation calls, NATO DIANA deadlines, NSSIF focus, Commonwealth and non-UK eligibility, volunteer routes, and FIRS guidance. Each update should be dated.

05

Release Guardrails

Facts age. This site should treat corrections as a feature rather than an embarrassment: claim, original wording, problem, source, revised wording, status, and date.

Before public release, links and official route details should be checked again. The current build is a static research companion, not a guarantee that eligibility, funding, clearance, or public-service rules are still current.

  • No operational defence advice.
  • No legal, immigration, procurement, security-clearance, or investment reassurance.
  • No unsupported claims of official status.
  • No imported local download, chapter, plate, or deck links unless those files are actually shipped with the static site.
