A million years ago, when I was in uniform, if there was a threat, I expected immediate notification of whatever was 1) known, and 2) expected. My Sailors knew, far better than me, what was important. Their experience and expertise allowed me to coordinate efforts to support them. They were better at their jobs, thank God, than I was.
When a unit is being fired upon, when a squad is pinned down by a sniper, or a ship is taking on water, the facts–however ugly–are important. If the troops at a certain position are under attack, it doesn’t matter if they are calm. Reality is reality. If they have a reasonable view of the operational environment, they will do everything to succeed.
Some politicians worry about how events make people feel. I recommend that they worry more about giving people the information to make rational decisions. Adults who feel badly, unless personally affected, will be fine.
Being upset is better than being dead.
