Rais then continued to study at the Meer Uitgebreid Lager Onderwijs (equivalent to Junior High School) near Mount Singgalang.

After that, he graduated with the rank of sergeant cadre in 1946 and was appointed as intel for weapons smuggling operations through the Dutch blockade and was sent to Tegal.

Rais was then sent to Palembang to meet Adnan Kapau Gani, the military governor of South Sumatra who prepared the logistics for his intelligence operation.

[3] Rais continued his education after the peace agreement was made and went to study at the LPPU High School for two years.

He then attended the Indonesian Army Command and General Staff College for two years until he graduated in 1956 with the rank of major.

[4] After serving for two years in South Sulawesi, Rais Abin was instructed by his superior to pursue further military education in the Australian Army Staff College, Queenscliff.

[4] Rais was informed about his nomination to the post of the chief of staff of the Second United Nations Emergency Force while playing tennis with Himawan Sutanto.

Susilo Sudarman, the assistant to the Commander-in-Chief of the Armed Forces at that time, Maraden Panggabean, called him to inform about the chief of staff matter.

[6] Rais later also assumed the post of the Deputy Commander of the Second United Nations Emergency Force on 5 June, making him an UN official.

[3] At the end of November 1976, Rais was told by the Chief Coordinator of the United Nations Peacekeeping Missions in the Middle East, Lieutenant General Ensio Siilasvuo, that Liljestrand would return home as he felt unhappy with the conditions in Egypt and Israel.

[3] While serving as the acting commander, the Under-Secretary-General of the United Nations for Special Political Affairs at that time, Brian Urquhart, kept pushing for the definitive appointment of Rais.

He received backlash from the United Nations Civil Staff Workers Union after one of his commander's secretary was dismissed by him.

[10] After retiring from the military, Rais was appointed by President Suharto as the Indonesian Ambassador to Malaysia and was inaugurated on 6 August 1981.

The ruling party in Indonesia, Golkar, lost in the country with only 40% of the votes, resulting in him being questioned by Leonardus Benjamin Moerdani, the Head of the Strategic Intelligence Agency at that time.

[16] Rais was appointed by the General Elections Commission as a member of the People's Consultative Assembly from the groups delegation, representing veterans.

[23] Dewi's mother, Ratu Aminah, was a women's rights activist who became an MP[24] and Deputy Speaker of the Constitutional Assembly of Indonesia,[25] while her father, Hidajat Martaatmadja, was a military officer with the rank of lieutenant general and had served several cabinet posts in Sukarno's government.
