What comprises a Brigade Combat Team in the given structure?

• A. Medical Battalion staff and two army medics
• B. Public health officer and environmental health officer
• C. Environmental Science and Engineering Officer (2LT-1LT) and One 68S20-30 (Prev Med Specialist) (E-5, E-6)
• D. Two entomologists and a nurse practitioner

Answer: (C)

The important idea here is the preventive medicine presence at the brigade level: a Brigade Combat Team relies on a small but integrated pair of specialists to manage environmental health and disease prevention in the field. An Environmental Science and Engineering Officer, typically a junior Medical Service Corps officer (rank from 2LT to 1LT), leads environmental health planning, water quality, waste and sanitation, pest management, and industrial hygiene to limit environmental risks. Working with them is a Preventive Medicine Specialist (68S) at enlisted ranks (E-5 to E-6), who conducts disease surveillance, vector control, immunizations and prophylaxis, field sanitation, and occupational health. Together, they cover both the engineering/environmental and medical prevention aspects needed to protect soldiers and maintain readiness in diverse operating environments.
