Halo see the difference 2

Remember the post that I made about the differences of the oldest and the newest Halo creatures . And I would like to make this post about more of amassing changes that Bungie made to the Halo creatures over the past years . But this time I would like to show the differences of the elite , grunt , spartan 117 ( Master Chief ) and also a creature that a google player called ( Nightwing ) told me to show by writing in the comments . By the way Halo fans remember that you can always write in the comments what a new Halo creature you wont me to show in my next Halo see the difference post :)
