Khattiya was a supporter of former Prime Minister Thaksin Shinawatra, and an opponent of the 19 September 2006 military coup d'état. He joined the Red Shirt movement that is considered close to Thaksin, protested against the coup and the military-backed government that took power afterwards. The pro-Thaksin camp returned to power after their electoral victory in January 2008, and Khattiya vowed to protect it against a potential new coup attempt—if necessary with military force. On 18 October 2008, during the anti-Thaksin
People's Alliance for Democracy (PAD) (or "Yellow Shirt") protests against the government, he announced his intention to "mobilise government supporters against any military attempt to seize political power", threatening that members of the pro-government
Democratic Alliance against Dictatorship (DAAD) would use
Molotov cocktails against any military vehicles taking part in a coup attempt. Because of his comments, the commander-in-chief of the Thai army, General
Anupong Paochinda, removed Khattiya from his post in the
Internal Security Operations Command (ISOC) and reassigned him as the army's
aerobics instructor. Khattiya organised the "Ronin Warriors", a group of a few dozen armed militants to fight against Yellow Shirts. He boasted of his fighters terrorising the protesters using
M79 grenade launchers, killing one PAD guard and injuring 40. On 14 January 2010, Army Commander Anupong Paochinda ordered the
suspension of Khattiya Sawasdipol after an inquiry committee found that Khattiya had openly supported the
DAAD, a political pressure group that called for new elections, which breached the principle that military officers not take sides in politics. The following day, Anupong's office in the
Royal Thai Army Headquarters was attacked by high explosive rounds fired from an M79 grenade launcher, leaving the office demolished but no one injured. Khattiya denied responsibility for the attack. ==Death==
