What is not a characteristic of reconnaissance patrols?

Reconnaissance patrols are designed primarily to gather information and require the ability to operate stealthily. One of their fundamental characteristics is to avoid combat whenever possible, as their mission focuses on observation and intelligence gathering rather than direct engagement with the enemy. The goal is to remain undetected to collect accurate and vital information about the terrain and enemy strength, which informs decision-making for future operations.

The characteristic of expending a lot of ammunition is inconsistent with the purpose and operational approach of reconnaissance patrols. Instead of engaging in combat and using substantial amounts of ammunition, the primary strategy is to remain discreet and collect data without direct confrontation. Thus, the option highlighting the excessive use of ammunition does not align with the distinguishing features of reconnaissance patrols.
