Security and Intelligence Agency of Tseng

The Security and Intelligence Agency of Tseng (Chinese: 曾國安全情報局; pinyin: Zhēnguó ānquán qíngbào jú; SIAT) is the Tseng Republic's primary national intelligence service. It is responsible for collecting, analysing, reporting and disseminating intelligence on threats to Tseng's national security, and conducting operations, covert and overt, within Tseng and abroad. It is headquartered in Tseng City.

The SIAT is considered to be one of the most effective security agencies in the world.

Founding
The SIAT was founded on December 8, 1959 as the Central Agency of Security (中央安全局; CAS) by then-president Jack Lin and former Dragon Agency (first intelligence agency of Tseng) operatives and agents. Elijah Tao was the first director.

Corruption, abuse, and controversy (1959-1980)
The CAS was ineffective and useless during the Dazhuo Era and the. Most agents and employees simply did nothing to combat the chaos and even if they did, it would be equal to doing nothing at all. In 1970, Stephen Yang ordered a CAS purge, and many of its employees were replaced and the CAS was renamed SIAT. Unfortunately, the new SIAT was considered to be worse. There were many controversies, like Operation Taiping, which made many random Chinese Tsengian citizens suspected of get interrogated using drugs like LSD or cocaine. The innocent Chinese citizens; as young as 13, were often interrogated without their consent, and the effects of the drugs led to addiction or death.

There were many unethical experiments done by the SIAT as well. One was Project Mercy, which was an experiment done to weaken the individual so the SIAT hoped to squeeze a confession out of the person.

Modern era (1980-present)
In 1980, president Thomas Lan-xiao ordered another purge. This time, the new employees were proved to be much better. By 1985, the SIAT had risen in status and is considered to be one of the elite spy agencies, responsible for foiling many scandals, such as the New Year's plot, Guenung Strait Crisis, the Minecraftian Strait Crisis, and operations in the UK, America, Afghanistan, Somalia, and China.

Training
The SIAT has schools in Tseng City (2), Qishan City (4), and Salvador, Sandao (2) The Tseng City school, Camp Zhihan is the first training school. It opened in 1960.
