Warhammer 40,000 guard regiments

This regiment was based off the US Green Berets in Vietnam

This regiments uniform and tactics were the mujaheddin (the Taliban that the soviets fought during their war in Afghanistan in the 1980s)

This regiments uniform and some other elements were inspired by the US Marine Corps

This regiment was based of the Soviet Red Army in WW2, especially their willingness to accept high casualties

This Regiments uniform drew inspiration from the German Army in WW1 and also the French and British Gas Masks in WW1. Also the tactics their mechanised infantry used are similiar to the German Army in WW2

This regiment (in my opinion) collectively represents the elite fighting forces of the world

This regiment drew inspiration from the 18-19th century Cossack (Russian) armies

This regiments (in my opinion) urban combat tactics were based on the IDF (Israeli Defence Force)

This regiments uniform is again inspired by several different WW1 armies
