What is a "Letter of Instruction" (LOI) used for?

A "Letter of Instruction" (LOI) serves as an essential communication tool within military operations, specifically designed to provide guidance and clarification for executing tasks and operations. This document typically outlines the parameters and intent of a mission, ensuring that all personnel involved have a clear understanding of their roles, responsibilities, and the expected outcomes.

The use of an LOI facilitates better coordination and alignment among various units and teams by laying out specific instructions, deadlines, and any pertinent information that supports the successful execution of tasks. It acts as a reference point for both leadership and team members, thus enhancing overall effectiveness and minimizing the potential for miscommunication during operations. By ensuring that everyone is on the same page, the LOI contributes to the operational readiness and effectiveness of military units.
