Which two modules of the CDC deal with anti-submarine warfare?

The correct choice identifies the two modules of the Career Development Course (CDC) that specifically address anti-submarine warfare (ASW). The ASW module is dedicated directly to anti-submarine tactics, techniques, and operations, providing foundational knowledge about submarine threats and the methodologies used to detect and mitigate these threats effectively.

Additionally, the ZULU module complements this focus by covering related operational considerations, enhancing understanding of the overall ASW environment. Together, these two modules equip personnel with the necessary skills and knowledge to conduct operations effectively against submarine threats, which are a critical component of naval warfare.

The other options do not correctly align with the focus on anti-submarine warfare. While they may refer to modules, they do not include both relevant components that specifically address ASW strategies and implementations. Therefore, recognizing ASW and ZULU as the correct modules is essential for comprehending the comprehensive approach to anti-submarine tactics and operations in naval strategy.
