Final answer:
No minimum number of U.S. military decorations is required before wearing a non-military decoration; however, proper order of precedence must be followed.
Step-by-step explanation:
The question relates to the regulations regarding the wearing of U.S. military decorations and how they pertain to the inclusion of non-military decorations. According to U.S. military uniform regulations, there is no minimum number of military decorations required to wear before a servicemember can wear a non-military decoration. However, it is important to follow the proper order of precedence when wearing decorations, with U.S. military awards generally taking precedence over non-military awards. Non-military decorations should be worn in the order that they are authorized by the Department of Defense or in accordance with other specific branch guidance.
