and direct fire is used on suspected positions to provoke the enemy to return fire and reveal their positions. Individuals that are not trained on recon by fire as a tactic or lack discipline are likely to return fire when fired upon.
Recon by fire works well on organizations that are under duress, tired or become complacent. A defensive operation that returns fire from multiple positions leads to a collapse of security if the majority of defensive positions are
revealed to the enemy prior to the actual attack. While in the defense individuals are to reframe from firing their weapons unless authorized or the threat is a significant danger to the force. All threat doctrine dictates that the lead echelon of an attacking element is designed to probe defensive positions in order to gather position information to better maneuver the remaining force against a perceived weakness in the defense.
