What Is a Sentinel?

A Sentinel is someone who chooses to stand permanent watch over the fallen of a specific agency. Not for a year. Not for a term. Permanently — as long as badge.nw exists. Your name appears on this agency's page, visible to every family member, every colleague, every person who comes here to remember. You are telling them: I see what this agency gave. I will not forget.

There is no higher act of remembrance on this platform than becoming a Sentinel. It costs less than a meal. It lasts forever.
