An abbreviation for "The Hand That Guides" a shadowy paramilitary organisation whose very existence is disputed. It reportedly governs all major events around the world and is believed to be made up of four incredibly powerful men known by their current psuedonym's as "Laslo, Ponzo, Scout and Rupe". There may be others involved in the "Clan".
They are a force to be reckoned with and should never be crossed.
Man, did you hear about that last HTG raid? It was fierce, the four of them killed two S.W.A.T. teams.
