What is reconnaissance by fire?

Reconnaissance by fire is a military tactic where units fire at suspected enemy positions in order to confirm their presence and gather intelligence on their locations. The primary goal is to provoke a reaction from the enemy, which can then provide valuable information regarding their strength, movement, and operational disposition. This is particularly useful when enemy forces are concealed or when visual confirmation of their location is not possible.

By firing at suspected positions, the attacking force can observe any incoming return fire or changes in enemy behavior, which helps to ascertain whether the area is occupied or if the enemy is moving. This tactic allows commanders to make more informed operational decisions based on the gathered information without directly engaging in a full assault or exposing their own forces unnecessarily.

The other options, while related to combat and reconnaissance strategies, do not accurately define reconnaissance by fire. For example, engaging targets to suppress enemy movement primarily focuses on controlling enemy actions rather than gathering intelligence. Firing to destroy fortifications emphasizes destruction rather than information gathering. Establishing visual contact involves direct observation, which is distinct from the indirect approach of reconnaissance by fire.
