Answer 3

Blackshirts
Inspired by the military prowess and black uniforms of the Arditi, Italy's elite storm troops of World War I, the Fascist Blackshirts were organized by Benito Mussolini as the military tool of his political movement.[1] The founders of the paramilitary groups were nationalist intellectuals, former army officers and young landowners opposing peasants' and country labourers' unions. Their methods became harsher as Mussolini's power grew, and they used violence and intimidation against Mussolini's opponents.

Brownshirts
The SA was the first Nazi paramilitary group to develop pseudo-military titles for bestowal upon its members. The SA ranks were adopted by several other Nazi Party groups, chief amongst them the SS, itself originally a branch of the SA. SA men were often called "brownshirts" for the colour of their uniforms (similar to Benito Mussolini's blackshirts). Brown-coloured shirts were chosen as the SA uniform because a large batch of them were cheaply available after World War I, having originally been ordered during the war for colonial troops posted to Germany's former African colonies.[1]
