Joint Fires Observer (JFO) Course Practice Test

Suppression means using fire to prevent the enemy from acting effectively by keeping their heads down and degrading their ability to observe, react, or fire. The statement that best fits suppression describes quickly bringing fire onto a target that is not actively engaging, because the goal is to deny the enemy the chance to respond and to degrade their capability to maneuver or shoot, even if they aren’t currently firing. Engaging a live target is a general attack rather than specifically suppressive action. Sanitation fire isn’t the standard term for suppression in this context, and marking a target with smoke is designation, not suppression.
