I require context.
There's a Grunt who serves aboard the Shadow of Intent who is a tall ass mother. Like, taller than a human. His height goes up to an Elite's shoulders.
Being the only grunt on the Shadow of Intent (and a Grunt at that) made him a prime target to be discriminated against and picked on.
Well, that was until he started wrecking all the Elites during sparring sessions. No matter how hard the Elites tried to beat him, this Grunt was throwing some hard ass punches and knocking the Elites on their asses. Then there's the story of how he ran into a Spartan and managed to overwhelm him/her to the point of retreating.
This was enough for Rtas to promote him to squad leader of an Elite Ranger unit. When faced with difficult situations, Rtas asked this Grunt for advice. In combat, he was a total badass. He choked out a Brute, engaged a Prelate in CQC, and was the quickest to recover from getting some of his neurons destroyed by a long range Halo pulse.
This guy is a fucking legend.
