Armor

Armor is a recurring element throughout the entire Red vs. Blue franchise, being suits of combat armor almost every single character is outfitted with head-to-toe. While, in the official Halo franchise, the Spartan armor is reserved solely for elite Spartan soldiers, the armor of Red vs. Blue seems to be the equivalent of generic military fatigues as every single soldier is equipped with a suit.

The coloring of the armor of each character is, in most cases, the singular thing that physically distinguishes them, and very few characters are ever seen outside of their armor no matter what, maintaining an anonymity for most characters. As the series constantly switched engines, armor models also constantly switched, and some characters are outfitted with a special model to illustrate their importance. A running gag is that Caboose is always outfitted with the oldest, Combat Evolved model while everyone else moves on to the newer models.

The durability of the combat armor is inconsistent. It's generally accepted that the armor can allow wearers to shrug off explosions and falling from massive heights, but gun-shots to the head are instant kills.
