In this update the arms have been completely overhauled and reworked.
The arms now have new textures and utilities that are visible on the arms. These are chosen based on the player model that the player has selected.
For example, if you select a ghille suit for your character, your arms will have visible leaves on them as a result. Each character now has its own arms. These include new arms for the american and german teams, for all six characters currently in the game.
This update provides a big improvement in terms of visuals and game-play changes and enhances the experience greatly.
