Final answer:
Recommendations for a Presidential Unit Citation, Navy Unit Commendation, or Meritorious Unit Commendation must be made within three years of the action, and the award must be made within five years of the recommendation.
Step-by-step explanation:
The recommendation for a Presidential Unit Citation (PU), Navy Unit Commendation (NU), or Meritorious Unit Commendation (MU) must be submitted within three years from the date of action or service. According to the regulations, the award must be made within five years thereafter. This means that if an act or service was performed by a unit, the recommendation for the award needs to be rendered no later than three years after this act or service has occurred, while the official awarding should be completed within five years from the date the recommendation was made.
