T.RexBrain

A knowledge base maintained by T.Rex Arms — an organized index of T.Rex’s published thought on weapons, gear, training, and the ideas that inform why an armed citizen prepares at all. Start with The Responsibilities of a Prepared Citizen for the foundation, then drill into whichever hub matches your current problem.

Hubs

1. The Responsibilities of a Prepared Citizen — Why a citizen prepares; the moral and historical foundation behind everything else here
2. EDC Essentials — Daily-carry knives, lights, medical, phone tools, comms
3. The Handgun Platform — Pistol models, IWB and OWB holsters, weapon lights, pistol optics, upgrades
4. Belt Setups — War belts, duty holsters, mag carriers, belt medical, mounting hardware
5. The Rifle Platform — AR-15, components, optics, lights, lasers, slings, magazines, ammunition, builds
6. Chest Rigs & Plate Carriers — Plate carriers, chest rigs, placards, MOLLE pouches, integrated medical loadouts
7. Armor & Protective Gear — Hard and soft armor, helmets, eye protection, hearing protection
8. Night Vision & Thermal — NVGs, thermal devices, mounting, IR illumination, weapon integration
9. Communications — Handheld radios, antennas, HF, ATAK, digital OPSEC, military comms, PACE planning
10. Training & Targets — Range philosophy, pistol and rifle training, T.Rex training products, tactical medicine
11. Tactics & Fieldcraft — Small unit tactics, patrol, reconnaissance, urban ops, defensive operations, civilian preparedness
12. Law & Politics — Second Amendment law, federal regulation, state-level law, advocacy, industry
13. History & Philosophy — American founding, English constitutional tradition, Protestant resistance theory, modern military history

How to use this site

Each hub page provides a brief overview and links to its sub-topics. Articles are cross-linked where concepts overlap — a discussion of rifle-mounted lights, for example, connects naturally to Night Vision & Thermal and Tactics & Fieldcraft. Follow the links that match your question rather than trying to read linearly.

If you are brand new, the recommended path is:

1. Read The Responsibilities of a Prepared Citizen to understand the why.
2. Move to EDC Essentials and The Handgun Platform — the gear most people need first.
3. Branch into Training & Targets early; equipment without skill is just weight.
4. Expand outward into belts, rifles, armor, night vision, and communications as your capability and context demand.

A note on recommendations

Where specific products are mentioned, they reflect T.Rex Arms’ informed opinions based on direct testing, fielding, and customer feedback. Gear recommendations change as products improve or disappear from the market. Principles don’t move as fast — focus on understanding the why behind a recommendation so you can adapt when the specific product no longer applies.

T.RexBrain is a living document. If you spot an error, an outdated recommendation, or a gap worth filling, reach out through T.Rex Arms’ official channels. The goal is to make this the single most useful resource for a citizen building serious capability — and that goal is never finished.
