I’m thinking of potential weapons of which a military force, low on conventional supplies and fighting with their backs to the wall, would use in either urban or open field environments. I’ve been doing research on uprisings throughout history, such as the Warsaw Uprising, the British Home Guard during World War II, the Hungarian Revolutions of 1956, and modern-day insurgent tactics used in Ukraine and the Middle East.
So far, I have ideas on types of weapons that would be utilized. There are the obvious ones, such as Molotov cocktails, IEDs, and guerrilla warfare. Depending on the environment such as urban cities, anti-tank traps such as hidden pits and general height advantage against soldiers and armored vehicles can be utilized. During the Hungarian revolutions, I remember reading that people would paint plates and run wires through them to make them look like mines - and have a few real mines hidden amongst them. You can easily make chemical weapons with household materials, so I assume those would be used by an army that was desperate to stop any enemies, war crimes be damned in their eyes.
What ideas or concepts do you have for improvised weapons that an insurgency army or a military force scraping the bottom of the barrel would use?
