 The PCG has an elite unit known as the Special Task Squadron (STS), which can be activated to conduct high-risk operations where high speed pursuits and increased firepower are deemed necessary to achieve their objectives.The unit played an instrumental role in the capture of one of the three armed robbers who infiltrated into Singapore by landing on Pulau Tekong in March 2004.In June 2017, PCG introduced a new front-line unit trained in counter-assault skills and to respond to terrorist attacks in Singapore's territorial waters.
