If you’ll note I mentioned that even gurillas need a plan and supplies. So substitute ‘an army’ for ‘effective fighting force’. But whatever, it’s all hypothetical.
No need for armies, supply lines, chain of command, etc. That shit will make you target and get ya in trouble.
A couple of motivated people don't need supply lines and big military strategic plans. For example, a bic lighter is cheap and can do significant damage/chaos. Now imagine 300 fed up people with bic lighters. It's easy to create total chaos and mayhem. The corrupt government knows all about this.
