What key use of visibility maximizes the effect of surprise during combat?

Using limited visibility to advantage is a key tactic that maximizes the element of surprise in combat. By recognizing and exploiting conditions such as darkness, fog, or other obscured environments, units can maneuver without being detected, position themselves strategically, and engage the enemy with greater effectiveness. This approach takes advantage of the enemy's inability to see or respond to movements, making it harder for them to anticipate or react to attacks.

In contrast, relying solely on nighttime movements or limiting operations to specific times can hinder flexibility and adaptability in dynamic combat situations. Operating only in daylight can significantly reduce surprise, as it allows the enemy to observe movement and plan counteractions. Ignoring visibility conditions altogether would lead to poor decision-making and increased vulnerability, as combat effectiveness greatly depends on understanding the environment and using it to one’s advantage. Thus, leveraging limited visibility ensures that operations are conducted stealthily and with the highest chance of achieving surprise.
