Final answer:
The specific form to be completed for Navy unit commendation recommendations is not provided in the reference text given, which focuses on the powers of the President as Commander in Chief.
Step-by-step explanation:
For Navy units, recommendations for the Presidential Unit Citation (PU), Navy Unit Commendation (NU), or Meritorious Unit Commendation (MU) should be prepared by completing a specific form in its entirety. However, the question does not include the name of the form required for this process, and this information is essential to provide an accurate response. As such, the proper form for these commendations is not provided in the given reference text. The reference text pertains to Section 2 of a document outlining the powers of the President as Commander in Chief, including granting reprieves and pardons, but it does not mention the form needed for unit commendations.
