Exactly. I don't understand why people are so avert to the word "panic". Extreme situations require extreme measures, which sure as hell look like "panic". If somebody is shooting at you - you're expected to panic and run and hide.

"Panic" is associated to irrational decision making, and is usually not what produces the best outcome. This is why there is a lot of training provided to professionals and even everyday people in potentially serious situations. If a plane crashes, they don't want you to panic and storm your way out of the plane, you'll just end up putting more lives at risk.
