Which of the following is a requirement for Marine Corps tattoos?

The requirement stating that tattoos must be one inch above or below the joint is the correct choice because it aligns with the regulations established by the Marine Corps regarding where tattoos can be placed on the body. This guideline helps maintain a professional appearance by ensuring that tattoos do not interfere with the uniform appearance of the Marines, especially in relation to joints which are typically more visible when wearing military attire.

The Marine Corps has specific policies governing the placement and visibility of tattoos to promote a unified and disciplined image. Tattoos must not be located in areas that would be exposed while in uniform, which has led to restrictions on placement near certain areas of the body, such as the neck, hands, and face.

Other guidelines stipulate that visible tattoos, especially on areas like the face or hands, are typically not permissible without special waivers, while there are strict regulations about tattoo size and placement around joints. The focus on keeping tattoos above or below the joint height ensures compliance with these standards while maintaining a level of aesthetics that is in line with military tradition.
