Supply operations are operations which allow players to obtain important resources, necessary to build their Operators and expand the RIIC, often with specific conditions that require players to adjust their strategies and team compositions. The higher the supply operation, the more valuable the rewards.
All supply operations except Tactical Drill are only available on specific days in a week, so the player must think carefully before spending 
Sanity to conduct them.
Before the A Walk in the Dust update, which introduced the Terminal rework, supply operations were divided into two groups: daily operations which included Aerial Threat, Cargo Escort, Resource Search, Tactical Drill, and Tough Siege; and chip operations which included Fearless Protection, Fierce Attack, Solid Defense, and Unstoppable Charge.
