Project War-Mantle was first mentioned in Rogue One: A Star Wars Story, when Jyn Erso was searching for the codename of the Death Star plans. In this episode, we discover that War-Mantle involved the conscription and training of non-clone troopers for the Empire.
The elite squad under Crosshair's command wear modified clone trooper armor, colored black with green lenses. They're also made to fit the soldiers' individual bodies, which differ from the uniform clone trooper frame.
Crosshair also has a new set of armor, bringing him closer to the new Imperial aesthetic. This includes the removal of his Bad Batch color scheme in favor of an all-black look, a green visor, and more standard armor plates.
The oxygen masks used by the Bad Batch are inspired by those worn by Han Solo, Leia Organa, and Chewbacca when they explored a cave (or so they thought!) in Star Wars: The Empire Strikes Back.
Wrecker converts the Marauder's top gunport into a bedroom for Omega -- her first home away from Kamino.
