Pipe Hitter;

Some one or a group of people who are willing to go to the extreme in order to get things accomplished. Most commonly refers to the special forces, but is not limited to that. Can also serve as an extreme marksman(s). Someone who will accomplish any task no questions asked. It is rapidly evolving to encompass all those who live life to the extreme.

When everyone on the objective must die and no structures need be left standing, call in the "Pipe Hitters".
