As the SWAT ability of other departments improved, the SAT became the "last ditch" of the Security Bureau of the National Police Agency, and opportunities to conduct direct domestic action decreased. In the Gulf Crisis of 1990, the SAP unit was dispatched to Saudi Arabia for non-combatant evacuation operation. During the Japanese embassy hostage crisis in Peru, the SAT had simulated raids on retaking buildings similar to the Japanese Embassy as a possible counter-measure to a similar incident on Japanese soil.
