What is your favorite armor customization?
Mark VI for me.
My preference always shifts between Recon and Mark VI. These two are my favorites, and I can never seem to choose between them!
Recon or Commando.
Raider
<----------------------- you can see it over there.
All Mark VI armor w/ Legendary visor and White (Or Darkest gray) with light blue (Teal)
Deadeye helmet with wetwork set
Recruit and War Master 
Mark V Chest and Helm with Ricochet shoulder-plating on the Right shoulder and whatever you want on the left, then Mark Gauntlets and Boots with Wetwork Visor, Blue Primary, Red Secondary. Looks AWESOME.
Helmet: Locus
Torso: Venator BYNT (Bayonet)
Left Shoulder: Rogue FCUS (Focus)
Right Shoulder: Rogue FCUS (Focus)
Forearms: Fotus
Legs: Fotus
Visor: Frost
Recruit or ODST. Sometimes Mark V or FOTUS to be funny.
To bad ODST and Mark V don’t register for Spartan Ops
