This thread is all about people who like to recreate their armours from older halos. I’ve posted before on how people would recreate their armour in 3, so know, I want to know how you would recreate your armour from Halo Reach to Halo 4.
Good idea 
this is the main reason why I’ve changed my armor to Air Assault because I’m such a low rank on reach tbh.
I chose mine based on the Graphic Novel series ‘Fall of Reach’ and its visual representation of prototype kits. So you can say mine is more or less book-heavy in design.
While the baseline Mark IV isn’t static, mine is based on the 2536 model ‘Mark V’ (yes, because that’s what it should be noted as) Red Team worn. Yes, it’s tank-colored, yes, it uses Recruit but then again you can look at the Fireteam Omega’s armor in earlier Halo Wars promotions: they’re almost identical by helmet. A Halopedia writer even commented on Recruit’s more antique look. I used ODST shoulders due to the canon being ‘initially developed for MJOLNIR’ this heavily implies being the first generation shoulder/arm protection.
My Halo: Reach armor:
Helmet: Gungnir/CBRN
Left Shoulder: Sniper
Right Shoulder: Security
Chest: Collar/Breacher [R]
Wrist: Assault/Breacher
Utility: Tactical/Soft Case
Visor Color: Gold
Knee Guards: Gungnir
The closest I can get in Halo 4 is this:
Helmet: Gungnir
Torso: Raider - It bears a a strong resemblance to the Collar/Breacher chest IMO.
Left Shoulder: Soldier ZENITH - For its low profile look of the Sniper.
Right Shoulder: Ranger STRIKE - I decided to shorten the Security’s size from Reach, similar to how the Commando shoulders were done.
Forearms: Twin-plated AEON - For its robotic look.
Legs: Recruit TIGER - The knee guards horizontalness(?) is similar to that of the Gungnir knee guards.
Visor: Legendary - I’ve been told multiple times that the Stalker visor would better fit Reach’s appearance, however, the Legendary visor was intented to be the Gold visor, so that’s what I’ll use it as. Honestly it doesn’t matter since the Gungnir helmet doesn’t even have a visor.
Reach Armor Set:
Helmet: Mark V
Shoulders: Mark V
Chest: Default
Utility: Default
Visor: Gold
Knees: Grenadier
Colors: Green/Green
Halo 4 Armor Set:
Helmet: Mark V
Shoulders: Mark V
Chest: Mark V
Forearms: Mark V
Legs: Mark V
Visor: Legendary
Colors: Green/Green
I wore full ODST in Halo: Reach so I can just rock full ODST or even use Recruit pieces in Halo 4.
I don’t rock ODST in Reach anymore though, but I like to keep my Reach and 4 Spartans separate as the art style is very different and they feature two different generations of Spartans; the Spartan-IIIs and IVs.
