The remaining Kibbo Kift members were transformed into a fighting force, still disciplined and healthy but now engaged in 'unarmed military technique'. Hargrave joined up with the Legion of the Unemployed in Coventry in 1930, and furnished them with green shirts and berets. By 1932, the Kibbo Kift were also in the green uniform, together forming the Green Shirt Movement for Social Credit. The Green Shirts soon became part of the street politics of the 1930s, engaging in battles with both Oswald Mosley's British Union of Fascists, the Black Shirts, and the Red Shirt supporters of the Communist Party of Great Britain. Hargrave designed a striking new flag for his Social Credit movements, the green and black double K device, which he christened the 'Key Symbol'. He also introduced a strong element of theatricality into the Green Shirts' political protest, with ritual marches round the Bank of England, drumming, 'street chalking' and publicity stunts such as throwing a green brick into 11 Downing Street.
