Okay kiddo, let me explain what a pioneer sergeant is.
A pioneer is someone who is interested in exploring or discovering new things. They like to be the first to try new things and to blaze a trail for others to follow.
A sergeant is a person who is in charge of a group of soldiers or people who are working together toward a common goal. They are responsible for making sure that everyone is doing their job correctly and that the group is working together as a team.
So, a pioneer sergeant is someone who is both a pioneer and a sergeant. They are responsible for leading a group of people who are exploring and discovering new things. They make sure that everyone is working together as a team and that they are all safe while exploring new areas.
Whether it's exploring new lands, mapping out uncharted territory or conducting scientific experiments, a pioneer sergeant is there to make sure everything runs smoothly and safely. They are an important leader who inspires and guides others to explore new frontiers and discover new things.
