At least two mounted regiments of Astrakhan Cossacks saw active service as part of the Tsarist armies in World War I.
During the Russian Civil War, Prince Tundutov formed a small army of Astrakhan Cossacks.
In times of peace, the Astrakhan Cossack Host supplied 1 cavalry regiment (4 sotnyas) and 1 platoon of guards (local police); in times of war - 3 cavalry regiments, 1 platoon of guards, 1 battalion of infantry, 1 special and 1 reserve sotnyas (to a Host total of 2,600 men).
In addition, one platoon of the Composite Cossack Regiment of the Imperial Guard was provided by the Astrakhan Host.
They had instead evolved into a number of separate districts, communities and farms located in clusters along the right bank of the Volga River between Astrakhan and Chenyi Yar.
