United States Armed Forces oath of enlistment in the context of "Red Square"

A military oath, also known as the oath of enlistment or swearing-in is an oath delivered by a conscript or volunteer upon enlisting into the state's armed forces. Various states have different phrasings of the oath, with the common component being the fidelity to the state and obedience to the superior officers. In the ancient times it was a very solemn procedure. In modern times, with many formal laws and regulations to maintain army discipline, it is still a solemn, but rather a formal event.
