How do I make clothes that will be different depending on what class (Rank) you are in the game?

I want to make clothes for an army game but the clothes are all different depending on what Rank you are so I am trying to find out is there any way to put all the different clothes into one and still have the clothes come out differently for what Rank they are?

script.parent.parent.ArmyGreens
if player rank = E1 use script.parent.E1ArmyGreens
if player rank = E2 use script.parent.E2ArmyGreens
if player rank = E3 use script.parent.E3ArmyGreens
if player rank = E4a use script.parent.E4aArmyGreens
if player rank = E4b use script.parent.E4bArmyGreens
if player rank = E5 use script.parent.E5ArmyGreens
if player rank = E6 use script.parent.E6ArmyGreens
if player rank = E7 use script.parent.E7ArmyGreens
if player rank = E8a use script.parent.E8aArmyGreens
if player rank = E8b use script.parent.E8bArmyGreens
if player rank = E9a use script.parent.E9aArmyGreens
if player rank = E9b use script.parent.E9bArmyGreens
if player rank = E9c use script.parent.E9cArmyGreens

There are way more but is there a better way to do this as I think the script is wrong and I cannot find a function to make this work.
