The Firefly is, first and foremost, a facilitator in up close situations in daylight or darkness.  As firefly experience accumulates, it’s clear how best to use them.  The basis of this opinion is centered in the “five legs”, so to speak, of the great majority of law enforcement or civilian experiences.  These five legs, though reported by others, are based on much personal research, mostly through consultation with those in the position to qualify as experts.  Those individuals have been SWAT personnel and SWAT leaders, in addition to one of the original founders of SWAT in America.  All have impressive real world resumes and, interestingly, have all come to similar deductions.  Rather than just personal opinions and experiences, I was so much more interested in similarity of conclusions.
