Step-by-step explanation:
On New Year's Day, it is a long-standing tradition for all officers of a military unit, organization, or installation to engage in certain ceremonial duties. These can include activities that connect them with each other and the community they serve, such as attending special social gatherings like a unit breakfast or participating in formal events. The exact customs can vary depending on the country and the specific branch of the military, but broadly, it involves a display of camaraderie and respect for the shared values and discipline that characterize military life. This sense of renewed identity and unity is crucial after undergoing rigorous training that includes clean inspections, correct marching formations, and the proper saluting of superiors. Celebratory customs may also reflect a connection with the broader society, such as the President's role in lighting the national Christmas tree or the annual Easter Egg Roll, which symbolizes a bridge between the nation's armed forces and the civilian population they serve.
