Dwarven Rifleman

The brave dwarven riflemen have faithfully protected their mountain kingdom of Khaz Modan ever since the battle of Grim Batol. Yet, as new threats arose to threaten their hard-won freedom, they offered their expert skills and tenacity to the Alliance. Using the legendary single-shot Blunderbuss Long Rifles, riflemen are excellent marksmen and can shoot both land based and airborne opponents.^{W3Man #?}

The dwarven rifleman is a native of the Ironforge clans who specializes in use of the long rifle. Typically, they use their climbing skills to work their way into a good vantage point, then rain death upon their enemy from above. Riflemen usually have long beards and wear blue, hooded cloaks. They carry a long rifle against their shoulder and scowls on their faces. Riflemen are dwarven sharpshooters.^{APG 188} Dwarven Riflemen are the first ranged units available to the humans.
