What is reconnaissance by fire?

Reconnaissance by fire is a military technique where a unit engages in firing on a suspected enemy position to gather intelligence about enemy strength, location, and operational capabilities. This method aims to provoke a response from the enemy, allowing friendly forces to assess whether the target is occupied or not based on the enemy’s reaction. If the enemy returns fire or reveals their presence, this can provide critical information that aids in decision-making for subsequent operations.

In contrast, aerial surveillance refers to the use of aircraft or drones to collect information from the sky, while covert movement focuses on stealthy troop movements to avoid detection. Electronic warfare, on the other hand, involves the use of electromagnetic spectrum capabilities to disrupt enemy communications and sensor systems. Each of these methods differs significantly from reconnaissance by fire in terms of tactics and objectives, which are aimed more at stealth or technology rather than direct engagement for intelligence purposes.
