Psycho Mantis is this in his first scene in Metal Gear Solid, where all the FOXHOUND members wear coats.Also, Ulysses wears a coat with the Old World flag on his back as well as a gas mask due to the radiation of The Divide.The overall outfit is slightly more protective but also lighter in weight. Lonesome Road introduces Riot Armor, which is basically the NCR Veteran Ranger armor from the core game with some stat bonuses and no faction association, as well as the Elite Riot Armor which throws in a minor case of Shoulders of Doom.The reason for them looking almost exactly the same is that the NCR adopted the Desert Rangers' (like Tycho, but as mentioned that only showed up in the flavour text) armor for their Veteran Rangers.In the Honest Hearts DLC, you can find the Desert Ranger combat armor, which is almost exactly like the Ranger armor save for being unaffiliated with a faction and has some distinct markings and writings by it's previous owners.
Counter to the omnious look, they're the New California Republic's elite force, spreading democracy at gunpoint.
