It looks like Call of Duty World League team camos may come to Call of Duty: WWII at some point. Users are reporting with the newest patch update for Call of Duty: WWII, playing in private matches with Bots enabled, some of the bots running around have team camos on their weapons.
Camos for OpTic Gaming, Team EnVyUs, eUnited, Rise Nation, Mindfreak, and Evil Geniuses were found, via @Nimble_COD. A high-res image of the OpTic camo was shared from @jdekk0s4.
Sledgehammer Games and Activision have not officially announced anything about CWL team camos yet, so stay tuned for any updates.
