Because I love how seriously the DoD takes newly invented terms, we have:

"The Integrated Survivability Onion"

https://cogecog.com/the-threat-onion/

1. Don't be seen.

2. Don't be acquired

3. Don't be hit

4. Don't be penetrated

5. Don't be killed

It's actually not a bad mental model training aid for teaching people who might find themselves in an active combat environment.
