What type of machine gun fire refers to shooting directly along the enemy's line?

Enfilade fire refers to firing directly along the enemy's line, meaning that the bullets travel parallel to the length of the enemy's formation. This type of fire is highly effective because it can maximize the impact on the enemy, often resulting in higher casualties. Enfilade fire takes advantage of the alignment of enemy troops or vehicles, allowing for a concentrated area of effect that can be devastating.

In tactical situations, understanding the benefits of enfilade fire is crucial for maximizing the effectiveness of machine gun employment. Proper positioning to achieve this type of fire allows for engaging targets with minimal exposure and can provide the firing unit with a significant tactical advantage.
