A skilled gunman always keeps his gun slightly tilted above the line of sight while shooting. Why?

Explanation

To understand why a skilled gunman always keeps his gun slightly tilted above the line of sight while shooting, we need to consider the physics of projectile motion and the effects of gravity on a bullet after it is fired.

### Step-by-Step Solution:

1. **Understanding Projectile Motion**:
- When a bullet is fired from a gun, it follows a parabolic trajectory due to the influence of gravity. The bullet's initial velocity is directed along the line of fire, but as it travels, gravity pulls it downward.

2. **Effect of Gravity**:
