IRA Green Book
Handbook for Volunteers of the Irish Republican Army

A crash course on how to ensure that all members of a force are aligned and focused on the same ends, and why you should be sure that local civilians are on your side.

From Catgirl Kulak:

Amazing Historical artifacts in the history of guerilla warfare and excellent primers on the correct attitude and organizational disposition any paramilitary group needs to achieve with regards to it’s internal moral clarity. Any paramilitary group which claims the right to defend itself, enforce justice as it sees it, and exclude or choose any larger political entity it may or may not recognize, cannot afford internal moral confusion as to its legitimacy and ability to enforce itself upon those who violate its codes. That might sound obvious, but even open uniformed militias with some official recognition or even state backing struggle with this. Hell official Nation state militaries often struggle with internal discipline and making soldiers comprehend their legal state… Now imagine how much stronger the struggle is when the uniform is civilian clothing, and ordinary police and governance by a hostile force are still there? Creating that moral clarity in the heart of volunteers, creating that shared doctrine, identity and life or death code… that’s what’s kept some version of the IRA operating for over 100 years, and judging by a recent documentary on “Narco-Paramilitaries” I just saw, they might last 100 more.
