Another hundred Chinese People’s Liberation Army (PLA) soldiers have completed a training course on the Russian-made S-400 Triumf long-range, interceptor-based air defense system (NATO reporting name: SA-21 Growler) destined for service in the Chinese People’s Liberation Army’s Rocket Force (PLARF), according to a Russian government source.
The PLA personnel that underwent training in Russia will reportedly be assigned to the second of two S-400 regiments to be stood up by the PLARF.
