Hailing from the shores of Tanaris, the swamps of Tol Barad, and now the mists of Pandaria came the call to Om'Garrosh'kar, or Journey for Garrosh as it is translated. The ranks of the force were filled from all over in the beginning and it's bulkhead was formed, an indomitable all Orc fighting force that hailed from a mixture of clans, though was predominantly Warsong driven. It's military leaders carried the banner of Hellscream into battle wherever they fought, their heroic nature only inspired more fanaticism and Orcish pride amongst the ranks of young and bloodthirsty Orcs. First to jump to any cause for Hellscream himself, the Garrosh'kar distinguished themselves with numerous victories over the Alliance on sea or land.
Now a new Om'Garrosh'kar has been called, leading this charge is a young and zealous Lieutenant of Hellscream's Reach, Unauk Warcharge of the Warsong clan. The Orc nation is surrounded on all sides, beset on all the corners of it's nation by those who hate it. Today's future for the survival of their race falls on the duties of it's youngest soldiers and still-standing veterans. There are those who align with the growing rebellion, scum, and even their own Orcish kin that fall in line with those traitors to Hellscream's will. The Alliance, the old enemy of the Horde who must be mercilessly wiped from existence and their bones broken into the fragments of archeology. Now it is your choice! Do you stand with Hellscream and serve his Garrosh'kar? Or will you be crushed underneath the might of the Horde?
The Garrosh'kar Skullcleaver are elite shock trooper units, mounted upon armored and unarmored Worgs for a mixture of light and heavy cavalry. In battle or out, they can dismount and double their purposes as a brutal foot force. Because of the Legion's reformation it's ranks are now fresh, only having a small number of veteran units to lead it's fresh recruits into battle; Through battle they will gain experience, the ranks will flourish, and eventually they too will become heroes of their race. The ranks of it's forces travel into battle behind it's brave officers, all wearing their sashimono to inspire loyalty, zealotry, and victory or death.
Aside from it's large fighting force and traditional rank and file forces, the Garrosh'kar also bolsters a secret police unit within it's organizational structure. The Orcs of the G'Thazag'Mo, inquisitors of Hellscream's name and law; None are friends to them, they search for treason among the corners and alleys of Orgrimmar and prosecute with the justices of Hellscream. Not known completely to the public or the Horde, they often employ agents and others to work and report for them. They are fiercely loyal to the Warchief and his reign, highly selective with what personnel they allow into their organization.
