Who is an Army leader? As depicted by FM 6-22 (Army Leadership) Whats your take on a leader and leadership?

An Army leader is anyone who by virtue of assumed role or assigned responsibility inspires and influences people to accomplish organizational goals. Army leaders motivate people both inside and outside the chain of command to pursue actions, focus thinking, and shape decisions for the greater good of the organization.

I always went by this:
Leadership is the process of influencing people by providing purpose, direction, and motivation while operating to accomplish the mission and improving the organization.
