It appears most good guys are Genre Blind. When military personnel or the police encounter the Monster of the Week, they invariably attack it with small arms fire. Unfortunately, this never works. The monster is always Immune to Bullets. This gives our heroes an opportunity to save the day with some Applied Phlebotinum. Very often in instances of this trope, a Technical Pacifist will urge the army/police/whomever to try and understand the monster before trying to kill it. Depending on the attitude of the series, they may either be considered a naive idiot or a paragon of virtue.
