Final answer:
The awarding of the Air Medal on a Strike/Flight basis typically involves a point system based on combat flights, but regulations for the required number of points vary by military branch and time.
Step-by-step explanation:
The Air Medal is a military award granted to U.S. Armed Forces personnel for single acts of heroism or meritorious achievements while participating in aerial flight operations. The awarding of the Air Medal on a Strike/Flight basis can vary based on military branch and specific engagement requirements. The Air Medal may be awarded on a point system, where a certain number of points, earned through combat flights, are required for the medal to be awarded. However, the exact number of points required is defined by the departmental regulations, and this can change over time. Generally, it reflects the frequency of flights, level of danger, and presence of enemy combatants.
