Which of the following describes permitted ethnic hairstyles for cadets?

The correct answer highlights the requirement for cadets to adhere to specific grooming standards outlined in NAVEDTRA 37116-K. This document establishes guidelines that detail acceptable hairstyles, ensuring uniformity and professionalism within the ranks. Following these guidelines helps maintain a disciplined appearance while allowing for some cultural expression through permitted ethnic hairstyles.

The other options do not align with the established standards. Allowing "any style, no guidelines" would lead to inconsistencies in presentation among cadets, undermining the discipline expected in military settings. The idea that "only short hairstyles are allowed" is too restrictive and does not account for the diversity of hairstyles that can still be in line with grooming standards. Lastly, stating "only specific traditional styles are allowed" misunderstands the flexibility that NAVEDTRA 37116-K provides while allowing for individual expression within established parameters.
