HKPF has six Mercedes-Benz Unimog U5000 tactical vehicles custom build for riot control. According to SCMP, they were “modified in France by a company specialising in heavy-duty, blast-proof armour plating.” The exteriors are also electrified to prevent people outside from entering. They were purchased for HK$5m each in 2010.
They were deployed on November 17th at Polytechnic University with an LRAD used offensively, despite HKPF telling LegCo they were only meant for “long-distance communication.” The LRAD was originally used to make a high pitched siren noise but switched to playing odd music as psychological warfare.
It’s become common to see the Unimogs used as a real APC. Police have been seen numerous times firing from the top hatch. They’ve also been used to clear barricades.
