Identify the traditional ethics upheld by Marines from the following:

The principle that "Marines take care of their own" embodies a core value of loyalty and camaraderie within the Marine Corps. This traditional ethic emphasizes the importance of looking after fellow Marines, fostering strong bonds among them. Taking care of one another ensures that every Marine feels supported, which enhances unit cohesion, morale, and overall effectiveness in fulfilling their missions. It reflects a deep-seated culture of brotherhood and mutual respect, where the well-being of a fellow Marine is prioritized.

The other choices, while they may relate to aspects of Marine culture or conduct, do not capture the essence of the traditional ethics upheld by Marines in the same way. The welcoming of newcomers is a positive trait, but it is a part of broader socialization rather than a foundational ethic. Showing vulnerability is not typically emphasized in the Marines, where resilience is often valued. Refraining from public displays of affection while in uniform aligns with professional conduct standards but does not reflect the deeper ethical commitment to solidarity and care that is central to the Marine Corps identity.
