Sintong Hamonangan Panjaitan (born 4 September 1940) is a retired Indonesian army officer who graduated from the National Military Academy in 1963.

Sintong's interest in the military emerged when he was seven years old when his house was often hit by P-51 Mustang bombs from the Royal Netherlands Air Force.

He obtained the Command attribute at Permisan Beach, on August 1, 1965, and returned to Batujajar for Para basic education, experiencing 3 falls.

After that Sintong was sent to restore security and order in Central Java, to lead a Platoon under Tanjung company to combat G30S supporters in Semarang, Demak, Blora, Kudus, Cepu, Salatiga, Boyolali, Yogyakarta and the eastern slopes of Mount Merapi.

[5] In 1969 Captain Feisal Tanjung included Sintong to persuade tribal chiefs in West Irian to choose to join Indonesia in the Act of Free Choice.

Although there were two fatalities (one pilot and one member of the Commandos), the operation was considered a success by the Indonesian government due to the safety of all the crew and other passengers on the plane, he and his team were awarded the Sakti Star and promoted one rank.
