Which term describes the deliberate collection of intelligence to discern enemy strength and disposition?

The term "Reconnaissance in Force" refers to a military tactic in which a force is deliberately sent into an area to gather intelligence about the enemy's strength and disposition. This tactic involves engaging the enemy to provoke a response that can reveal their positions, capabilities, and weaknesses. By applying this approach, commanders aim to obtain actionable intelligence to inform subsequent operational decisions.

In this context, "Reconnaissance in Force" is effective because it not only seeks to gather information but also serves to test the enemy's defenses and tactics. Distinguishing it from other methods like surveillance, which often involves passive observation without direct engagement, or various types of recon that may focus on specific areas or zones without the intent to confront, highlights its specific purpose in active intelligence gathering concerning enemy force levels.
