Collar attachments

Collar is a group of chest pieces for use in conjunction with MJOLNIR Powered Assault Armor. The Collar accessories are compatible with MJOLNIR Mark V. Aesthetically, all MJOLNIR/Collar variants have one thing in common; they are extended so they cover more of the wearer's pectoral region and extend around the neck to the far upper back, forming a 'collar', hence the nomenclature. This extension of the player models' aesthetic appearance does not affect their hit boxes, however, it can make for a slightly more visible target, especially in the case of the up armored [G] Variant.

Trivia

• Collar/Grenadier [UA] is the chest piece worn by Jorge-052, and even when the player has equipped the chest piece, Jorge's Spartan tag (052) can still be seen on the side of the armor piece. However, despite the fact that Jorge's chest plate has two colors, both different from the olive drab of his main body, the player's version can only be the same color as his main color, even the faceshield.
• When wearing Collar/Breacher [R], in first-person, you will always see the FJ/Para shoulder piece regardless of which one you wear.
