Final answer:
Military decorations typically require recommendations to be submitted within two years of the related act or service. The award is then conferred as soon as possible, with specific time limits varying by award.
Step-by-step explanation:
The timeline for submitting recommendations for most U.S. military decorations requires that the recommendation be entered into official channels within two years of the act, achievement, or service that is being recognized. Once the recommendation is submitted, the goal is to confer the award within a relatively short period, preferably close to the date of the distinguished act. However, specific time limits for awards may vary, and there are exceptions to these general guidelines, such as for service-specific awards or under special circumstances.
