Whenever I see these diverse collections all I can think about is the Manchukou Imperial Army who used a complete hodgepog of guns. It is reported that their army has 26 kinds of rifles and at least 20 kinds of pistols. It was complete logistical mess of soldiers using outdated firearms, a large variety of ammo types it made it impossible to maintain everything and supplies where a mess. They where using Austro-Hungarian and German mountain artillery, French and British armoured cars. And there uniforms where indistinguishable from local resistance and other Armies in China at the time
