STAR is the acronym for the Singapore Police Special Tactics And Rescue. However when the MH 653 hijack took place no such unit existed. There was a motley part time bunch called the Police Tactical Team which had tactical training with the IDF. I am not sure they would have mounted an Entebbe type assault had MH 653 landed at Paya Lebar, but I am sure they would have scrambled the Skyhawks to intercept and divert it to Tengah or Seletar.
