Rank (Halo Wars 2)
From Halopedia, the Halo wiki
Game rank in Halo Wars 2 is the rank given to a player in-game. Halo Wars 2 offers two kinds of ranking scheme; a Competitive Skill Rank (CSR) similar to Halo 5: Guardians' Arena and an XP-based Spartan Rank more related to systems seen in Halo: The Master Chief Collection's updated rank scheme or that seen in Halo: Reach.
Spartan Rank is an XP-based rank scheme that levels a player up based on XP accumulated and gametime played. There are 99 levels to achieve, with each level-up earning the player a Blitz pack. XP can be gained by playing all gamemodes (such as campaign, Terminus Firefight, non-competitive playlists and others), and is not indicative of a player's skill level.[Note 1]
