Which exercise would be best for developing both strength and teamwork among Marines?

Log exercises are particularly effective for developing both strength and teamwork among Marines due to the physical demands and collaborative nature of the activity. When participating in log exercises, Marines must work together to lift, carry, and maneuver heavy logs, which requires close coordination and communication. This collective effort reinforces the importance of teamwork as every member contributes to the success of the exercise.

The physical aspect of the exercise promotes strength building, as handling the log engages multiple muscle groups and enhances both individual and group physical conditioning. Furthermore, the challenge of moving a substantial object forces Marines to rely on one another's strengths and abilities, fostering trust and camaraderie among team members.

In contrast, the other options, while beneficial for various skills, do not emphasize the same dual focus on strength and teamwork as log exercises do. Sustained guerrilla exercises might enhance endurance and tactical skills, orienteering focuses on navigation and problem-solving, and combatives centers on martial skills rather than collaborative strength building. Thus, log exercises stand out as the best choice for simultaneous development in these areas.
