This is more commonly recognized as the armor worn by the protagonist in the Fallout 4 trailers- much akin to the Dragonborn’s iron armor in The Elder Scrolls V: Skyrim. Generally, save for a few exceptions, Armor pieces in Fallout 4 can be categorised into 5 main types: Combat, Leather, Metal, Raider and Synth.
Missing Fallout 4’s most powerful armor is pretty easy, given that it’s inside of an unmarked building. You are able to update your game within few clicks. This odd inconsistency is not only distracting and immersion-breaking, but it also blocks a huge chunk of the screen with that ugly HUD. With so many fun and interesting mods to discover, we've decided to compile some of Better Settlers by Thom293 addresses this issue by adding over 240 settler variants to the game. Without Mods, combat armor is not available but Metal Armor will be so, make sure you buy and hang onto this armor for you and your Guards.
