Grunts aren't just Grunts. They are superunatural organic unrealistic 3-D animated fake and idealistic beings too! *gasp for air* 
  
I mean, come on! Grunts can do a lot more than those 1 mile an hour Hunters, Acrobatic kicking Elites, or those old fat hairy Brutes, right? 
  
Grunts are famous for: 
  
-Blowing the hell out of you with a Fuel Rod gun. 
-Running at you wielding 2 sticky grenades, prepared to kill even 10 of their own teammates. 
-Being in the way and accidently getting ran over by a friendly ghost. 
-Being hit in the head just because players love seeing confetti fly out. (What a terrible birthday present for the poor ole' Grunt) 
-Not being able to jump except when a grenade lands near you. 
-Being so easily killed, they are killed mostly because they're in the way. 
-Being target practice. 
-Top notch grenade spammers. 
  
Over all these amazing (and rather annoying) Achievements... Grunts deserve the rights a Spartan does!
