Jump Before The Bullet

The most well-known sacrificial move in fiction history.

When someone Jumps Before The Bullet, they throw themselves in front of an incoming projectile attack from an enemy to shield somebody else. Most likely, the selfless act will result in a Sacrificial Death, having the shielded person mourn the passing of their ally. If the jumper can survive the shot (and they likely do), they get their Dying Words out before breathing their last breath. It's expected that the shielded person then either cries, yells the jumper's name, and/or becomes a Beast Fueled By Rage And Hatred to destroy the enemy and avenge their protector.
