Question: In what year was the military organization founded that Dagan was conscripted into in 1963? Passage 1:This is a list of campaigns personally led by Mehmed II or Sultan Mehmed the Conqueror (30 March 1432 – 3 May 1481) (Ottoman Turkish: محمد ثانى, Meḥmed-i s̠ānī; Turkish: II. Mehmet; also known as el-Fātiḥ, الفاتح, "the Conqueror" in Ottoman Turkish; in modern Turkish, Fatih Sultan Mehmet; also called Mahomet II in early modern Europe) was Sultan of the Ottoman Empire twice, first for a short time from 1444 to September 1446, and later from February 1451 to 1481. At the age of 21, he conquered Constantinople and brought an end to the Byzantine Empire, transforming the Ottoman state into an empire. Mehmed continued his conquests in Asia, with the Anatolian reunification, and in Europe, as far as Bosnia and Croatia. Mehmed II is regarded as a national hero in Turkey, and Istanbul's Fatih Sultan Mehmet Bridge is named after him.
 Passage 2:The British eventually recaptured Grappler from the French in September 1809 in the daring raid on Saint-Paul on the Île de Bourbon (now Réunion) from the nearby British-held island of Rodrigues. The British force consisted of a naval squadron under Commodore Josias Rowley and an Army force under Lieutenant Colonel Henry Sheehy Keating. The Army contingent, which consisted of 368 soldiers from the 1st Battalion of the 56th Regiment of Foot under the command Keating, embarked on HMS Nereide under Captain Robert Corbett, Otter under Captain Nesbit Willoughby and the East India Company schooner Wasp under Lieutenant Watkins. The rest of Rowley's squadron, the flagship , and the frigates under Captain Samuel Pym and HMS Boadicea under Captain John Hatley joined off St. Paul. These ships contributed an additional 236 seaman volunteers and Royal Marines to the assault. The entire invasion force then embarked on Nereide, as Corbett had experience with coastline of the Île Bonaparte coastline. On the early morning of 21 September the force seized the port of St. Paul. There they destroyed its defences and recovered a number of British vessels. Nereide and the landing party captured the 44-gun French frigate Caroline, and recovered Grappler as well as the East Indiamen (850 tons (bm) and pierced for 30 guns) and (820 tons (bm) and pierced for 26 guns). The expedition also captured three small merchant vessels (Fanny of 150 tons, and Tres Amis and Creole of 60 tons each), destroyed three others, and burnt one ship that was building on the stocks. The British did not sustain any loss on board the squadron or to their vessels. The British completed the demolition of the different gun and mortar batteries and of the magazines by evening and the whole of the troops, marines, and seamen returned on board their ships.
 Passage 3:Dagan was conscripted into the Israel Defense Forces (IDF) in 1963. He was considered for the elite Sayeret Matkal unit, but ended up joining the Paratroopers Brigade. He completed his compulsory service in 1966, but was called up as a reservist in 1967, and fought in the Six-Day War as an officer, commanding a paratrooper platoon on the Sinai front. In the early 1970s, he commanded an ad hoc undercover commando unit, known as Sayeret Rimon, whose task was to combat the increasing violence in the Palestinian territories. In 1971, he received a Medal of Courage for tackling a wanted terrorist who was holding a live grenade. Dagan later fought in the 1973 Yom Kippur War as an officer on the Sinai front, and participated in the crossing of the Suez Canal. During the 1982 Lebanon War, he commanded the Barak Armored Brigade, and was one of the first brigade commanders to enter Beirut. In the 1990s, he held a series of high-level positions in the IDF command, eventually reaching the rank of Major General before retiring from the army in 1995, after 32 years of service.
