The US shows often try to hide what they are by embracing the "support the troops and honor their sacrifice" message. These Chinese films seem to be a bit more up front about what they are. Bear in mind though that it is literally illegal for a film in China to in any way portray the People's Armed Forces or the government in a negative light. I was just watching the underrated HBO miniseries Generation Kill about US Marines in Iraq. It's a brutally honest portrayal of the Marines and their experiences and it neither judges nor celebrates them. You couldn't make a similar series about Chinese troops, not within China's borders at least. You'd likely end up in jail if you tried.
Also keep in mind that if Hollywood wants the military's cooperation in the production of any war movies for the most accurate consulting possible, they must paint the military in a positive light. For example, every killing must be a life and death, "it was him or me" type of scenario, rather than just having soldiers heartlessly mowing everyone down that enters their line of vision.
Frankly, I like more honest looks at the military, such the 1990s remake of "Invasion of the Body Snatchers", which was a metaphor for the military stripping away the individually of soldiers in exchange for being part of a hive mind. This the same reason why the first act of "Full Metal Jacket" during the training half of recruitment is universally considered the best section of the movie, whereas the movie takes a less entertaining turn once the soldiers go to the actual war.
