What are the two keys to success in combat?

The two keys to success in combat primarily hinge on effective communication and teamwork. These elements are crucial because combat situations often involve multiple units and personnel working together to achieve a common goal. Proper communication ensures that all members of the team are aware of current situations, strategies, and any changes that may arise during the engagement. This flow of information helps to synchronize actions among Soldiers, leading to a cohesive effort that is essential in the chaos of battle.

Moreover, teamwork enables individuals to leverage each other's skills and strengths, creating a more formidable unit than any individual could achieve alone. Soldiers must trust each other, understand their roles, and support one another to effectively respond to the dynamics of a combat environment. Thus, while the other options may contribute to a soldier's readiness or skill set in specific scenarios, it is communication and teamwork that are foundational for coordinated and effective operations during combat.
