Which of the following is NOT a focus of Strike Warfare?

Strike Warfare primarily concentrates on the offensive aspect of naval operations, specifically targeting enemy assets to diminish their combat effectiveness. This includes objectives such as neutralizing enemy weapon systems, attacking tactical targets on land, and destroying manufacturing facilities that can support hostile operations. Each of these focuses directly contributes to weakening the enemy's capabilities and reducing their capacity for sustained military action.

Controlling sea choke-points, however, pertains more to the broader area of maritime strategy and sea control, which involves establishing dominance in pivotal areas of the ocean to ensure safe passage for naval forces and commercial shipping. While it is critical to overall naval strategy, controlling choke-points is not a primary focus of Strike Warfare, which is more concentrated on direct attacks to degrade the enemy's operational capacity rather than securing geographical areas.
