What good is a fully stocked bug-out bag if your house burns down with it inside?

A cache solves that problem. Supplies pre-positioned where you can reach them when your primary stores are gone, destroyed, or inaccessible — that's the insurance policy most preppers never build.

This guide is adapted from TC 31-29, the U.S. Army Special Forces manual that has been the gold standard for military caching operations for decades. Bob Mayer didn't just study it — he trained on it and taught it in the Special Forces Qualification Course.

That institutional knowledge is translated into plain language for civilian preparedness.

You'll learn how to:

• Apply the military's seven planning factors to every cache decision
• Choose a site that survives construction, seasons, curious hikers, and years of neglect
• Package supplies to last — waterproofing, corrosion prevention, container selection
• Use concealment, burial, and submersion — and when each method is right
• Establish precise, unambiguous reference points so you can find it when it counts
• Emplace and recover without leaving a trace
• Distribute sensitive items across multiple caches so one loss isn't catastrophic

The fundamentals are timeless. Plan carefully. Package properly. Choose the right site. Hide it well. Document everything. Master those basics and you'll have a skill set that could prove invaluable when it matters most.

Start small. Start now. Before you need it.
