Fel Orc Grunt

Fel Orc Grunts appear in the Blood Elf campaign, while Chaos Grunts are used in the campaign after Grommash Hellscream drinks from the Chaos Well. They both have a different red skin color and glowing yellow eyes compared to normal orcs.

Trivia

 * The only difference in stats between a Chaos Grunt and a Fel Orc Grunt is their cost and Armor, Chaos Grunts cost the same as their base unit and have what's displayed in the campaign as normal armor.
