I guess the swastika ones would work pretty good, since the star is spinning, and the angled spikes are tangent to the rotation, and therefore would cut into the direction it was thrown.
People need to keep in mind that the tank was designed in 1933-34 so it was released while the Vickers-6 ton was first being iterated upon. The varius versions of the M-3 and M-5 light tanks weren't piers but vehicles with almost a decade of wartime development to to draw on and a close examination of what worked and didn't for the French and British though perhaps some lessons didn't stick. The fact that the Japanese army seemed to fail to develop the 95 much and actually reverse some progress in armored doctrine is worthy of condemnation. I used to mock Italian designs but even as shit as they are they speak to a poor industrial base not idiocy. The Japanese did develop a theoretical pier to the M-4 Sherman in '44 armed with a 75mm cannon but it was held in reserve on the home islands like the majority of the 47mm armed "medium" tanks. The idiocy of the axis lies with their leaders far more than with their engineers. That being said even amongst the allies the M-4 Sherman is without pier. You send four Sherman to take on any single enemy tank because that is the smallest unit they are tasked To use and the four will show up. If there are more than one enemy tank then it is a platoon so you send an company. If you are fighting fair you are fighting wrong.
I grew up in a town in Trinidad that was situated near a US Army air base that was built during World War II. An older man there told me that there was a landfill near the town where trucks from the base would arrive every month to dump tons of perfectly good food items. Why? Because the air transport would arrive every month to replenish the air base's food stores and there was simply no storage apace for the the previous month's stock.
You eat potatoes when you can find and uproot them. You literally chew wood bark to alleviate your hunger when you do not. You use a piece of old dirty rag to "filter" dirty poodle water and drink it. And that while you are tired, sleep deprived, ambushing, skirmishing the enemy every night and almost every day. One lucky day, you manage to capture one of their supply convoys. Such a joy! Military rations again, boys! And one of the trucks you captured is loaded with individually packed, ready to eat... Birthday cakes. The enemy is providing his troops means to celebrate their birthdays. That is what a cake does to enemy morale.
From the book Sons and Soldiers by Bruce Henderson, a captured Ritchie Boy (I believe Werner Angress)was talking with his German captor during D Day and learned that his captor knew that they were going to lose the war solely because he found chocolate in his rations. I always found that so interesting.
Dude has no food and water for 3 days, hunkered down in a hole in a South Pacific Island. Americans come in eating ICE FREAKING CREAM. That's morale...
..... the weight of armor was irrelevant to them being in mud. Bad terrain, disorganized attacks, etc was the cause. Thinking that Armor was the cause when the English wore Armor as well shows how little youn understand about the battle itself
Problem is Japan had the same problem Italy did. Competent tank force in the interwar period but not enough industry to modernize and keep up with developments once the war started. Ha-Go was perfectly serviceable for when it entered service in 1936. But once you get to 1941 its hopelessly obsolete.
Keep in mind the german swastika was a case of cultural appropriation as some high up members were looking to legitimize their reign with occultism and stuff.
