Final answer:
The military is the group that typically utilizes an autocratic leadership style, as it requires clear direction and quick decision-making within a structured hierarchy.
Step-by-step explanation:
The group that would use an autocratic leadership style is the military. An autocratic, or authoritarian, leader issues orders and assigns tasks with little to no input from group members. This style of leadership is characterized by a top-down communication pattern and is focused on meeting goals efficiently, often in situations where decisions need to be made quickly or are informed by a high level of expertise. In contrast to other leadership styles like democratic or laissez-faire, the autocratic style is less about consensus and more about clear, decisive direction, which is essential in military operations where structure and hierarchy are crucial for operational effectiveness.
