Difference between SWAT and people's armed police is SWAT listens to local police, while people's armed police is an active service military force similar to army national guard(but full time)
essentially, the ZSL92/WZ551 family had three variants used by the PAP and local police:
- WJ-94: 4x4 variant used by PAP; very rarely seen nowadays
- WJ-03: 6x6 variant used by PAP and SWAT; also rather rare nowadays
- WJ-03B: new variant, still used by PAP
- GA-06: 4x4 variant used by SWAT during overseas UN peacekeeping missions
Nowadays local SWAT typically uses the Saber tooth tiger(chinese modified F550) or T-rex(chinese modified Ram 5500) SWAT vehicles that are more dedicated to this role; UN peacekeeping police is no longer managed by local SWAT but rather secret service who use the VP11(also known as the snow wolf) MRAP.
