Gazyr

A gazyr (via Russian: газырь from Turkish hazır, "ready", ultimately from Arabic; Chechen: Бустамаш bustamash, Georgian: მასრები masrebi) is an implement to hold a rifle charge: a tube with a bullet and a measure of gunpowder or a paper cartridge.

They were carried in gazyr bags or in rows of small pockets on the breast.

Later, gazyr pockets became a distinctive element of national dress of the peoples of Caucasus, such as the chokha.

[1] Gazyr breast pockets ("gazyrs") were borrowed by Russian Cossacks, together with other elements of Caucasus peoples' outfit, as part of their military uniform.
