For at least a decade, there has been this overhyped, hard sell campaign by "Lt. X", he claims to be a "former Military Intellegence officer" and "Only Because Of A Military Legal Loophole Can I Reveal The Terrifying 'Decide-Dominate-And-Destroy' Shocking Martial Arts Secret Banned By Congress That Can Transform ANY MAN (Or Woman) Into A Walking, Breathing Weapon Of Mass Destruction."
The problem is (a) a military intelligence officer would have almost NO combat experience (they don't do that, it's not part of the job) and (b) there are no military loop holes for teaching this stuff, congress has not banned it etc.
Lt. X is in fact a "composite character" i.e. made up. He is the "brain child" of Chris Pizzo and Damian Ross. Neither to the best of my knowledge are "ex Military intelligence officers", nor trained by the Military.
