To truly excel, you need a highly efficient Mother Base. Here are some tips:

- Recruit Constantly: Always be Fultoning high-rank soldiers. Replay Extra Ops that are known to have good recruits.
- Prioritize R&D: A strong R&D team unlocks better weapons and items faster, which makes all other missions easier.
- Outer Ops Management: Regularly send your Combat Unit on Outer Ops. Choose missions that offer high GMP or valuable resources you need. Match soldier stats to mission requirements for higher success rates.
- Mess Hall & Medical: Don't neglect these. A high-level Mess Hall keeps morale up and stamina recovery fast. A strong Medical Team heals injured soldiers quickly, getting them back into action.
- Intel Team for Support: A high-level Intel Team provides better radar, enemy intel, and support during missions, which is invaluable.
- Dismiss Low Ranks: Once your base is full, dismiss E and D rank soldiers to make room for A and S ranks. This keeps your overall base level high.
A well-oiled Mother Base machine will provide you with the best gear and support, making even the toughest challenges manageable.
