Who is one of the Drill Sergeants in Bravo Company?

DS Coffey is an important part of the training team in Bravo Company, serving as one of the Drill Sergeants. Drill Sergeants play a crucial role in the training and development of recruits, guiding them through various phases of their military education and ensuring they meet the rigorous standards expected of soldiers. DS Coffey's direct involvement in the training process contributes significantly to the discipline and skills of the trainees.

In contrast, MAJ Hernandez and CSM Gonzalez hold leadership roles, but they are not Drill Sergeants; rather, they oversee broader aspects of the Company or Battalion. DS Ware might also be involved in training, but the specific identification of DS Coffey as one of the Drill Sergeants highlights his role in the day-to-day training and mentorship of recruits, making him the correct choice in the context of the question.
