In a real encounter, knowing the difference between concealment and cover can decide who walks away.
Concealment hides you. Cover protects you.
A bookshelf, curtain, or drywall might block a silhouette, but it will not stop a round. Concrete, steel, or an engine block will.
The instinct to tell one from the other cannot come from theory. It comes from repetition and stress-tested training.
At ISTM, we teach first responders and civilians how to identify cover, move through it, and shield others while providing medical care under fire. The difference between knowing and reacting is what keeps people alive.
What was the first time you realized how limited “cover” can actually be in a real environment?
