Question: During which decades was the terrorist group , which launched Operation Primicia, active?
Context: Operation "Ababeel" was the code-name for the military operation planned by Pakistani Armed Forces to capture the Siachen Glacier in the disputed Kashmir region, precipitating the Siachen Conflict.  On 13 April 1984, India launched Operation Meghdoot to pre-empt Operation Ababeel, which resulted in Indian troops successfully gaining control of the entire Siachen Glacier. On May 13, 1948, a day before the state of Israel was proclaimed, the Haganah launched Operation Shfifon (Hebrew: מבצע שפיפון‎ ‎ , "lit."  Operation Cerastes Cerastes) with the aim of capturing the British outposts in the Old City of Jerusalem and preventing the Arab forces from taking control of them first.  Such an eventuality had long been anticipated, and plans prepared called Operation Shfifon ('horned viper'; some translate it as 'Serpent') and quickly followed by Operation Kilshon. Soldiers of Egypt (Ajnad Misr in Arabic) is an active Salafist Islamist militant group that has been operating near Cairo, Egypt.  The groups was founded by Humam Muhammed in 2013, after he split away from the Ansar Bait al-Maqdis militant group.  The group claims that its attacks are "retribution" for the August 2013 Rabaa Massacre; notably, the group targets only security forces.  It has warned civilians of the presence of bombs that it has placed.  The Cairo Court for Urgent Matters declared the group a terrorist group on 22 May 2014.  It has been a Proscribed Organisation in the United Kingdom under the Terrorism Act 2000 since November 2014.  The United States Department of State designated it a terrorist organization on 18 December 2014. In early December 2013, the French army launched an operation in the Timbuktu region, where many jihadist movements were reported.  One hundred vehicles and helicopters were involved.  Neither the Malian forces nor MINUSMA took part in the operation.  The French combed an area between the towns of Bouje-Baya and Araouane and attacked a katiba of Al-Qaeda in the Islamic Maghreb.  A Malian officer said that "the elements of the terrorist group fought to the end.  At least 19 members of the movement were killed.  There were no wounded or dead on the French side. Operación Primicia (] , "Operation Scoop") was a large guerrilla attack that took place on 5 October 1975, in Formosa, Argentina.  It was the largest attack ever launched by the paramilitary group Montoneros, which attempted to seize the barracks of the 29th Forest infantry regiment.  This attack worsened the Dirty War, and indirectly led to the 1976 Argentine coup d'état the following year. The 361st Infantry Division (German: "361.  Infanterie-Division" ) was an infantry division of the German Army during the Second World War, active from 1943 to 1945.  It was redesignated as a "Volksgrenadier" division in 1944.  It saw active service on the Eastern Front when the Soviets launched Operation Bagration, during which it suffered significant losses.  It later fought in France before being absorbed by the 559th "Volksgrenadier" Division on 10 March 1945. Celle Hole (German: "Celler Loch" ) was a breach in the outer wall of the prison of Celle, Germany.  First used on July 25, 1978, the name was part of a campaign by one of the West German secret services (Landesbehörde für Verfassungsschutz) and the GSG 9 in an attempt to lay blame on the Red Army Faction, West Germany's most active and prominent left-wing terrorist group.  However, the incident was revealed in 1986 to be a plot by the government, a False flag operation, much to the embarrassment of the government.  The Verfassungsschutz used the name 'Operation Fire Magic' (German: "Aktion Feuerzauber" ). Beginning on the night of March 23, 1945 the 21st Army Group under Field Marshal Bernard Montgomery launched Operation Plunder, as a part of a coordinated set of Rhine crossings.  The crossing of the river Rhine was at Rees, Wesel, and south of the river Lippe by the British Second Army, under Lieutenant General Sir Miles C. Dempsey (Operations "Turnscrew", "Widgeon", and "Torchlight"), and the United States Ninth Army (Operation "Flashpoint"), under Lieutenant General William H. Simpson.  The First Allied Airborne Army conducted "Operation Varsity" airborne landings on the east bank of the Rhine in support of Operation Plunder, consisting of U.S. XVIII Airborne Corps, the British 6th and the U.S. 17th Airborne Divisions. Operation Tinombala is a joint-military operation conducted by the Indonesian National Police and the Indonesian Armed Forces to capture and/or eliminate members of Mujahidin Indonesia Timur (MIT), an Indonesian terrorist group which supports ISIL and was commanded by Santoso.  Recently, the Indonesian military and police succeeded in killing Santoso, but General Tito Karnavian continued the operation to ensure the region's safety from the remaining eleven members of the group.  Central Sulawesi governor Longki Djanggola praised the operation for its relatively humane methods, since several leaders of the group were successfully captured alive. Montoneros (Spanish: "Movimiento Peronista Montonero-MPM" ) was an Argentine leftist terrorist and urban guerrilla group, active during the 1960s and 1970s.  The name is an allusion to the 19th century cavalry militias, called Montoneras, who fought for the Partido Federal during the Argentine Civil Wars.
