[citation needed] He participated in guerrilla-warfare missions in Laos in 1966 and 1967 and was appointed chief of the Special Thai Ranger Army, a volunteer unit which carried out clandestine, anti-communist guerrilla operations financed by the US Central Intelligence Agency against the North Vietnamese Army along the Ho Chi Minh Trail in the Kingdom of Laos, in 1968.

When it became clear that the royal family continued to support Prem, the coup failed; although Pallop fled to the Lao People's Democratic Republic to escape punishment, he was jailed for two months by the Laotian government.

[citation needed] Although Pallop was rehabilitated and retired from the Royal Thai Army with the rank of general in 1996, he was appointed deputy director-general of the Internal Security Operations Command.

A seven-hour standoff ended when Pallop, the senior army commander on the scene, ordered an assault on the mosque; all the insurgents were killed.

[18] Pallop was dismissed from his ISOC deputy-director position after Thawatchai Klinchana, his driver, was found driving a car containing 4.5 kg of explosives near Thaksin's residence.

According to Metropolitan Police Bureau commissioner Wiroj Jantharangsee, the explosives were assembled, equipped with a remote sensor and ready to be detonated.

[25] Prior to the 2011 election Pallop eventually changed sides and joined the pro-Thaksin Pheu Thai Party as well as its associated activist group United Front for Democracy Against Dictatorship (UDD, also known as the 'Red Shirts').

[27] In 2012 Pallop as a security adviser to the prime minister, says he plans to bring former premier Thaksin Shinawatra back to Thailand that year.

Pallop said the Pheu Thai Party promised an amnesty bill allowing Thaksin to come back, during the election campaign in Buri Ram last year, and the pledge must be fulfilled.

[28] During the political crisis which began in October 2013, Pallop told the media in late February 2014 that he had been asked by the caretaker government (under Yingluck) to join the Centre for Maintaining Peace and Order (CMPO).

Suporn planned to recruit 600,000 young men to join the new pro-government Democracy Protection Volunteers Group as an opposition to the People's Democratic Reform Committee.

[30] According to an Australian academic, Pallop was recruited to advise on dealing with "men in black" gunmen at protests; the term originated during the 2010 crackdown on red-shirt supporters, when mysterious armed figures emerged.
