70s was the decade when terrorism was at its height. Waves of aircraft hijackings, kidnappings etc and militaries around the world had no dedicated trainings and tools against it. 1972 Munich massacre was the trigger for many countries to realized that they need to have capabilities against the new trends.
Months after 1972 Munich massacre, SAS made Pagoda Troops as first dedicated anti-terrorism and anti-hijacking unit under Counter Revolutionary Wing (CRW). To spread the capabilities to the whole 22nd SAS Regiment, they rotated its 4 squadrons with one for training, one ready on call, one on long duration training like jungle training etc and another one ready themselves to replace the unit on call. Don’t asked who invented flash grenade which first intended against 70s threats lol
Israel, for decades their threats always revolves around terrorist style attacks, even 1968 one of El Al flight was already hijacked. One of the biggest coordinated aircraft hijackings that all the aircrafts were landed on PLO occupied airfield in Jordan, the Dawson’s Field hijacking was aimed against them, with the hijackers used the hostages as bargain chips for Israel to released Palestinian political prisoners in Israeli jail. Jordan thought they were enough with PLO in their country launched what called as Black September campaign after the hijackings and pushed PLO out of Jordan, mainly to Lebanon. Even though Israeli couldn’t doing anything about it, but they knew what’s gonna coming to them. Their first successful hostage rescue against aircraft hijackers was Operation Isotope, just months before Munich massacre.
West Germany where the event happened also made their dedicated counter-terrorist unit under the German Border Police –its original job was to guarding inner German border between the west and east–, the GSG 9, Border Guard Group 9. Ulrich Wegener was the first commander of GSG 9 and he was usually became the consultant for military around the world for counter terrorism. West German magazine Stern said he was also took part in Entebbe raid as “guest observer”. One year later he led GSG 9 raid on hostage rescue mission of Landshut hijacking in Mogadishu.
US like others, not gonna far from that three, and they were late to the game actually. Some may gonna say late 70s Delta Force, okay, but don’t forget about Detachment A, Berlin Brigade. Because of rising threat of aircraft hijacking during the 70s, Detachment A which at first had a role for unconventional warfare, they started to trained with GSG 9 for the possible scenario of Pan Am hijacking by West German Red Army Faction (RAF) or others in Berlin (West) airports.
Indonesia, you know by yourself.
