By 1963, he also assumed the additional role of Prime Minister, which completed the structure of 'Guided Democracy', and was named "President for Life", also with army assistance, the year after. At the same time, the Indonesian government started sending their troops on UN peacekeeping missions. The first batch of soldiers were sent to Sinai, Egypt and were known as Garuda Contingent 1. Garuda Contingent I began its first deployment January 8, 1957 to Egypt. Garuda Contingent I consisted of the combined personnel of the 15th Army Infantry Regiment Territorial Command (TT) IV / Diponegoro, as well as one company of the 18th Infantry Regiment TC V / Brawijaya in Malang. This contingent was led by Lt. Col. of Infantry Hartoyo which was later replaced by Lieutenant Colonel of Infantry Suadi Suromihardjo, while his deputy was Major of Infantry Soediono Suryantoro. The contingent departed on January 8, 1957, on board the Douglas C-124 Globemaster II transport aircraft of the United States Air Force for Beirut, the Lebanese capital.
