  • Collar/Grenadier [UA] is the chest piece worn by Jorge-052.
  • When wearing Collar/Breacher [R], in first-person, you will always see the FJ/Para shoulder piece regardless of which one you wear.
  • Collar/Breacher and Collar/Breacher [R] both appear to have seven shotgun shells attached, possibly a reference to Bungie's obsession with the number 7.
