In The Lord of the Rings, Legolas is naturally a master of this skill.

Joker: How can you shoot women and children? See Hero-Tracking Failure for when the villains fail to do this and Wronski Feint for an aviation variant. There may also be a delay between squeezing the trigger and actually releasing the beam. Perhaps they are taking into account very long ranges - 20,000 miles is a tenth of a light-second - and absurdly high speeds a ship moving at Earth escape velocity covers a lot of ground in a tenth of a second. Regardless, plenty of space combat games ignore this. Lasers, due to moving at the speed of light, should not be expected to follow this rule. This is the source of the 'firing solution' you'll sometimes hear shouted about on the bridge of naval vessels (or, less commonly, by artillery gun crews). This is also relevant in sea and air combat with broadside weapons: even if the target isn't moving, the shooter usually is. The hitscan model is sometimes retained when energy, laser, or other lightspeed weapons are available. Slower projectiles obviously need more lead time, and sniping can be a real nightmare. But today games are much more complex and realistic, and a more moderate form of leading the target has reasserted itself. The alternative was the Painfully Slow Projectile, where the player not only has to lead the target, but actually shoot the bullet past where the enemy is, so the enemy will indeed walk right into it. Video Games used to avert this trope with hitscan weapons, which were an Acceptable Break from Reality because of engine constraints hitscan weapons didn't so much use 'bullets' as simply hurt whatever was under the player's crosshairs at the time, regardless of distance. It's why you use clay pigeon traps for hunting practice, and is a key element in air-to-air gun combat. This is called leading (or windage), and is a Real Life tactic and training method. Instead of a Hero-Tracking Failure he will get the target cleanly because they almost literally ran into the bullet. When gunning for a fast-moving or far-away target, he won't aim at the target (often shocking companions) and instead aim where they are going to be. However, The Gunslinger knows that this isn't some holy trinity of death, and is the more lethal because of it.

Guns are incredibly psychologically powerful as symbols, let alone weapons.
