xuzhou like stalingrad was a communication hub but the kmt fought a more fluid battle than the russian due to the lack of heavy weapons. The russian even outgunned the german in term of artillery pieces. The most efficient arms of the red army was its artillery component. If Hitler had not interfer and let the german general staff along, the result of WW2 would have been very different.
Tai er zhuang was the first war movie i saw in cinema. kmt even deploy its shock troops, the big sabre troops who get into close quarter fighting against terrified japs with only the sabre. the german doctrine appeal to chiang and model the kmt officers corp to the german. and the germans also help the kmt greatly, even allow the kmt to produce the superb mauser bolt action rifle and the world beater MG34. So there u have it, in terms of small arms, chinese equipments were much better than what the japanese were using yet the kmt troops suffer defeat after defeat against the IJA.
getting back to the thread, one must admit that the german uniforms were superbly design that make it appealing. The only other uniform that come close is the US marine corp dress uniform.
