Thanks to Irfan for sharing these.

APMM (Agensi penguatkuasaan maritim Malaysia)  aka Malaysian maritime enforcement agency Special Task and Rescue posted up these pics. They seem to be using Sig 553s. They’re equipped with the Team Wendy Exfil Ballistic helmet and the Smith Elite OTW goggles which were provided by Cresdo, the company Irfan works for.
