1-31. An Army leader influences others to accomplish missions. A leader has the opportunity to lead when assigned responsibility, assuming a role, or being an informal leader within a team. Leaders motivate people both inside and outside the chain of command toward action or to change their thinking when appropriate. Formally or informally, regardless of position or rank, all Army members can find themselves in situations to lead and influence others. Leaders who adapt their actions based on the dynamics of a situation achieve the best possible outcomes. Leaders take into account the level of their experience or skill, and their authority.
