Orc Crest
From WoWWiki
The symbol of the Orcs was used as the icon of the Horde under Warchief Thrall. The wolves represent the Frostwolf Clan, as well as the orcs' kinship with wolves, and the crossed axes symbolize their skill in battle. The symbol of the Horde at the center of the shield represents the orcs in the crest of the Horde.
