Persistent across deployments: operator traits and skill trees, FOB upgrades and stash, weapon unlocks from Weapon Manuals, Bounty Leaderboard standing, XP and rank; no XP penalty for a failed exfil.
Activision's list: Operator Traits and skill trees (per Operator), FOB upgrades and Stash contents, weapon unlocks from extracted Weapon Manuals, Bounty Leaderboard standing, and XP and rank progression [1]. The 9 Oct guide adds [2]: DMZ Cash in the Bank, Resources, Ingredients and the Stash are shared by all your Active Duty Operators; Recipes and Weapon Manuals become permanent unlocks once extracted; DMZ XP counts even on a failed exfil; an Operator who dies keeps their Traits if you pay to recover them, but not their gear (MIA system), and items outside Secure Slots are lost. Whether a wipe ever happens is in open questions.
