What does broken arrow mean?
Means a lost nuclear weapon.
Basically it’s a holy shit we’re in BIG trouble. .send help NOW. .the enemy is everywhere and we’re outnumbered.
From Wiki;
“Broken Arrow, a military distress signal used to call in all available close air support in order to prevent an area from becoming overrun.”
This was done in the movie “We Were Soldiers.”
What it means now;
“Broken Arrow (nuclear), an accidental nuclear incident that involves nuclear weapons, warheads, or components but which does not create the risk of nuclear war.”
