First, in 600 words or less, consider the Air Force and a sister service component of your choosing and explain two capabilities that exist in both and why retaining these duplicated capabilities in both services enhances joint operations and preserves service competencies.
Second, for the remainder of the essay and in 400 words or less, consider the Air Force and a sister service component (can be the same or different component) and explain one capability (different from the first part of the essay) that exists in both and argue why one of the services should have primary ownership of that duplicated capability and that doing so will not sacrifice the effectiveness of the joint force.
When supporting your arguments, consider Service doctrine, Service capabilities, the nature and elements of joint operations, other course and external material, and examples.
