It's just painful to watch, especially how it starts with generic stock sounds and music. It has NOTHING to do with imitating what is useful, but everything to do with dressing up as some other country for perceived marketing benefits.
Most of the equipment they used(I'm not talking about the rotary gun here) is a direct imitation of the US army despite clearly having an alternative that PLA actually use, the first-gen Mengshi armoured car that they used is a direct external imitation of the Humvee, but the second and third-gen armoured cars have completely moved beyond looking like Humvees and PLA actually uses them. There is also plenty of recent PLA uniform is perfectly marketable yet distinct at the same time.
They don't have to(it would be easier if they don't), yet they still deliberately went out of their to cosplay the US army, as if it would make it more marketable. Make no mistake, there is still a prevalent notion within China itself that foreign looks(like the US military) are considered cool and marketable despite China having come a long way since then.
They are not selling to the US army or its allies so they are literally imitating the opponents' looks for the sake of it and it's pure cringe. Seriously, those who worship foreign looks/equipment for no good reasons need to straighten their backbones.
I don't understand why this short video has stirred up so much raw emotion.
First, the video is made by a relatively small team, I follow one of them on Weibo, dude is just a retired PLA solider who works as a tactical instructor now. He makes videos occasionally on Bilibili, but its all relatively low budget video and I feel like his video style is very similar to that of Lucas from T-rex arms (which is not a bad thing, Lucas makes pretty awesome stuff on Youtube). The location they used to showcase the guns is at the testing facility at one of the arms manufacture, so the video is not sponsored by the PLA, I feel like it is more of a self production by the arms company itself (think of it as a Norinco ad, not a PLA ad).
For a small budget production from non-professionals, I think it is not a bad look. In fact, most of the advertisement for small arms looks like this now, it is somewhat of a industry standard. There is nothing Western about this video, unless you are arguing that the video editing itself is Westernized, but film is a Western invention itself. Do you want to see they advertise a rotary 50 cal machine in traditional Chinese opera?
Second, there is nothing inherently bad about imitating other nation's behaviors or looks, especially in the military realm. Whatever works, works, and that is that. The suit and tie is without a doubt a Western invention, does that mean all Chinese need to wear the traditional Han Fu to be proud of their culture? Wheat as a food is brought to China during the Han dynasty when the Silk Road opened to the West, and does that mean eating wheat means you are Kowtowing to the West? Gunpowder is invented by the Chinese, but Westerner was not ashamed to use it to commit genocide and lay waste to the various peoples of the world. Picatinny rail is an American invention, but it works, so adopting it is a wise choice, not a submissive act to obey Western norm. If American style Fast helmets and plate carriers work, then why not adopt it? Do you want to see PLA soldiers dressed like this when they go to war? Is this traditional Chinese enough for you?
Third, the PLA doctrine is for the PLA. Exported arms is exported arms. Just because you export arms that are compliant to the Western style, does not mean you are abandoning the PLA doctrine. This one short video on Weibo means nothing at all, it is just a ad, and that is that. It is not a statement by the PLA, nor does it mean anything significant. Stop overreacting to this.
You know, the Chinese was extremely proud of everything Chinese prior to the first Opium war. A direct result for this arrogance and unwillingness to acknowledge the power of industrialization is the Century of humiliation that has shaped the modern Chinese psyche (which includes this unconscious worship of the West that you hate so much). Many Chinese's mindless worship of the West is indeed a significant problem, but it takes time to rebuild confidence in the Chinese tradition and find the Chinese way.An extremely unwise way is to reject everything Western during this path towards rejuvenation.
