What is required to establish Direct Service Connection (SC) for a disability?

To establish Direct Service Connection for a disability, all specified elements are essential and must be demonstrated. This means there must be evidence of a current disability, proof of an event, injury, or disease that occurred during military service, and a clear link or nexus between that event and the current disability.

The requirement of a current disability indicates that the veteran must have a recognized medical condition that significantly impacts their health or functioning. Additionally, demonstrating an event, injury, or disease in service is critical because it provides the context and enables showing how the condition developed after military service. Lastly, the nexus is crucial as it connects the dots between the in-service event and the current impairment; without this connection, it would be challenging to prove that the disability was incurred or aggravated by military service.

Thus, all these components collectively fulfill the criteria needed for Direct Service Connection, confirming that option representing all three elements is indeed correct.
