How would Armed Forces and similar organizations and structures work in different types of Anarchism in practice?
I've heard ancaps discuss how this would work in their ideal type of "Anarchy" if you can call it that...(http://www.anti-state.com/article.php?article_id=330 this is what most ancaps have described to me.)
Thanks to the Spanish Civil war we saw a glimpse of what this would look like in Anarcho-syndicalism.
There have been communist orientated "Anarchist" armies and other militant organizations throughout history.
In whatever state of Anarchy you envisage what would armed forces and the like be like? What would they look like? What would be the foundation? Would they strictly defensive? Etc.



Can comment on articles and discussions
this depends a lot on context. all revolutions have some sort of defense. but in a peaceful state of anarchism I don't see why there would be cops or "workers militia" patrolling the the streets. people always say stuff like "but what about serial killers?" but this is a ridiculous justification for police to be on patrol. police don't patrol the streets on the off chance that they might witness a serial killing.
