From the Rugs of War website:
Rugs of War is a project which investigates the history, iconography, production and distribution of “the war rug”.
The traditional knotted rugs made by the semi-nomadic Baluch people of northern Afghanistan are famous for their distinctive designs, their rich yet subdued palette and the quality of their construction and materials, which feature traditional patterns and motifs.
The “war rug” is an evolution of these Baluch rugs through the inclusion of militaria and other references to the experience of war and conflict in the region. These significant changes became apparent almost immediately after the Soviet invasion of Afghanistan in 1979, when rug-makers began incorporating complex imagery of war planes, helicopters, machine guns, maps and texts into their designs.
