On this date in 1980, after a six day siege, the Special Air Service stormed the Iranian embassy in London to free the hostages held by the terrorists inside. Prior to this incident the SAS had kept a low profile, mostly being thought of, when thought of at all, as the guys that drove around the desert in jeeps during WWII. Now live TV cameras caught images of black-clad men stacking at doorways and rapelling through windows, and people who had been unaware of the existence of the "dynamic assault" saw one in action.
Suddenly, Anti-Terrorist forces were the "in" thing and the 22nd Special Air Service Regiment were the rock stars of the British armed forces and the HK MP5 was the dream gun of nerdy gun nuts everywhere. You couldn't swing a cat in the entertainment industry without hitting a dramatization, a fictionalization, an Americanization, or a lying technical advisor who claimed he'd "Been With The Regiment". If it hadn't been for an unavoidable failure in OpSec on that May day in 1980, Rainbow Six might never have existed, and then what would a generation of gun nerds and video gamers have done with their spare time?
