Perhaps it was a bit too easy, but you have to remember that this isn't exactly Spartan armor. I mean, it is, but it's not on the same level? There seem to be no shields on them, which would take the brunt of the knife, and if he hit the guy in the visor or neck, then it likely would have killed them. Honestly, if this show truly lived up to the Halo canon, then perhaps it would be an issue. But you have to think, this is the show that a few bullets took off a foot, injured South to a point of nearly killing her, one shot injured Agent Tex's arm during Season 9. So the armor isn't nearly as strong in the show, and never has been, as it is in the Halo canon.
