What specific concern did Dahl and Coke share regarding military operations?

Dahl and Coke were particularly concerned about air superiority during their military operations. Air superiority refers to the dominance of one force's air power over another's, allowing them to conduct operations without the threat of interference from enemy aircraft. This concern is significant because having control of the skies can greatly influence the outcome of ground operations and overall military strategy. In the context of Dahl's experiences in the war, achieving and maintaining air superiority would have been crucial for ensuring the safety and efficiency of ground troops, as well as for the success of military missions. While ground troop movements, naval blockades, and enemy reconnaissance are all important components of military strategy, the specific focus shared by Dahl and Coke on air superiority emphasizes its critical role in their operational planning and execution during their time in the military.
