What is an Army "Standard Operating Procedure" (SOP)?

A "Standard Operating Procedure" (SOP) in the Army is a set of written instructions that provide detailed guidelines for conducting routine functions and processes within a unit. These procedures are essential as they ensure consistency, efficiency, and safety in operations. SOPs are designed to streamline tasks and help personnel understand how to perform their duties according to established protocols. This contributes to mission success by helping to minimize the potential for errors and miscommunication.

The other options do not accurately reflect the definition or purpose of an SOP. While combat strategies are important, they are not what an SOP focuses on; instead, SOPs are more about standardizing routine tasks. Informal procedures during training lack the formalized nature and structure of SOPs, which are written and systematic. Lastly, evaluating supply chain effectiveness is a separate function that may use SOPs as a reference but is not synonymous with the definition of an SOP itself. Hence, the option that describes an SOP best aligns with its purpose in maintaining operational standards within the Army.
