"Reconnaissance-in-force" (RIF) is a method of probing an enemy's position. An attack, even with a small force, may get a strong reaction by the enemy. Hopefully that reveals the enemy's strength, deployment, and other tactical information. The RIF commander can fall back with the information or expand the conflict into a full engagement. Other methods consist of hit-and-run tactics using moving very fast. In some cases light-armored vehicles are used for added fire superiority, as the need arises.
