The APC post... okay, let's get to the bottom of it. My comment of the linked Armored Personnel Carrier article was it (the article) wasn't positive feedback on Chinese APC. What part of that troubled you?
Why do you keep asking this question like it hasn't been answered numerous times?
1. Your source is questionable. It's an odd forum with no author's name emblazoned with weird phrases with a cult-like mural as the background. It's not professional at all nor does it strive to be. It doesn't even mention what the vehicle was hit with, what model, how large the IED. Hell, it doesn't even say what year it happened in. Cheap Chinese vehicle blew up from IED in Kenya is all it provided.
2. People have already told you, IEDs blow up armored vehicles from any country, and have provided evidence. So if someone bought a Chinese military vehicle but had negative reviews because it was blown up by a weapon that it was not made to withstand, that's the operator's fault. You can't buy a Camry, drive it off a cliff, then blame Toyota that you couldn't just flip it back over and keep driving home. (Do we even have official comments from the operator?)
Why do you keep asking what's wrong with your post as if no one could come up with anything other than FU?
