Who is responsible for Level 1 project planning?

Level 1 project planning is typically the responsibility of the S3, who is the operations officer within a military unit. The S3 is primarily involved in the management and coordination of all operational aspects of the unit, which includes planning and executing various projects. The S3 oversees the overall mission strategy, ensuring that all elements of the project align with the unit's goals and objectives.

In the context of military operations, the S3 is tasked with developing detailed plans, timelines, and resource allocations that guide the successful completion of projects. This role requires a broad understanding of the operational environment and the ability to coordinate efforts among various personnel and units.

Other roles such as Company Commanders, Crewleaders, and Field Officers play important parts in project execution and oversight, but their responsibilities typically fall within a different scope. Company Commanders focus on personnel readiness and leadership at the company level, Crewleaders manage specific teams and tasks on the ground, and Field Officers execute plans directly in the field. Therefore, while they contribute significantly to project outcomes, they do not handle the overarching planning at the Level 1 stage as the S3 does.
