Black Ops Cold War may be last year's Call of Duty, but the game received an update on December 6 to synchronise Military Ranks and Prestige Levels ahead of Vanguard's Season 1. The patch notes also detail nerfs for the Marshal pistol and include new unlock challenges for past DLC weapons.

Synchronized Leveling With Vanguard

Starting on December 8 with the launch of Vanguard's Season 1, Military Rank and Prestige progression will be synchronized with Vanguard across titles. This means players will begin the season at the Military Rank or Prestige Level they've currently reached in Vanguard, or Military Rank 1 if they haven't played Vanguard yet. From there, players will be able to progress through Vanguard Military Ranks across Black Ops Cold War, Warzone, and Modern Warfare to unlock weapons, equipment, killstreaks, and other seasonal content for use in Vanguard and Warzone.

Additionally, each new Prestige Level will award players with a Prestige key, tier skip, emblem, and sticker in Black Ops Cold War, and once they’ve reached Season Level 50 in Season 1, they’ll unlock the exclusive "Duck Hunt" Shotgun Weapon Blueprint to use in Vanguard and Warzone.
