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 of it.
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 unbreakable anonymity. As the series constantly switches game engines to film on, armor models also constantly switch, 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, though it's generally accepted that the armor can allow wearers to shrug off explosions and falls from massive heights, but gun-shots to the head are instant kills.

- Although Caboose is written as wearing the older Mark V Halo: Combat Evolved armor starting in Reconstruction, the models used to represent him across all-usable engines typically only wear the Mark V helmet. In Halo 3, the helmet was the only Mark V piece available. Although the full Mark V armor was available to wear in Halo: Reach and Halo 4, Rooster Teeth's standard practice is to swap the standard Blood Gulch soldier armor setup with the Mark V helmet to represent Caboose and simply refer to it as the Mark V armor.
- Many armor models made specifically for Poser-animated scenes are combinations of armors from different Halo titles, such as the Insurrectionists and certain configurations of the Meta's armor.
- The only characters in the entire franchise who don't wear full-body armor are Leonard Church, Aiden Price, Malcolm Hargove, all characters in the "Club", "Call", "Consequences" trilogy, and Allison.
