Which documents serve as the primary AC manuals for defense acquisition?

The correct choice encompasses the most comprehensive and essential documents that guide defense acquisition processes. DoDD 5000.1 and DoDD 5000.2 provide overarching policies and principles for defense acquisition. DoDD 5000.1 outlines the key roles and responsibilities in the defense acquisition process, while DoDD 5000.2 details the specific phases and procedures that must be followed.

In addition, the Defense Acquisition Guidebook (DAG) offers detailed guidance and best practices on how to implement the policies set forth in the DoD directives. Lastly, AR 70-1 provides Army-specific policies and guidance related to the acquisition of material resources and systems, making it critical for aligning Army acquisition with the broader DoD framework.

By including all these documents, the answer reflects a complete understanding of the regulatory framework that governs defense acquisition, ensuring that practitioners are equipped with the necessary guidance to navigate the complexities of the acquisition lifecycle.
