If he actually served as a Marine, he needs to get back to the training he received with the Corps. Marines do not just slander their enemies with innuendo and make scurrilous accusations that may or may not be true! They MAKE NO ASSUMPTIONS WHATSOEVER! They diligently study the enemies tactics, who they are, where they fight, why they fight, and how they fight. He learns their strengths and weaknesses in order to be better prepared to defeat this enemy!
Seems to me some things that could and should be implemented in this spiritual warfare we are waging!
