The clusters may be loaded with fragmentation, antitank, incendiary, or toxic chemical bombs.
The clusters are painted olive drab or gray. Markings on the olive drab clusters are black. Markings on the gray clusters are black and white. The designation of the bombs contained in the cluster is stenciled on the front half of the cluster.
