Beyond generic recruits, Peace Walker features several 'legendary' soldiers with exceptionally high stats or unique skills. These individuals are often hidden in specific Extra Ops or require special conditions to recruit. Examples include:

- Hideo Kojima: Found in Extra Ops 067. You need to find him hiding in a truck.
- Monster Hunter Characters: Available through specific collaboration Extra Ops (e.g., Rathalos, Tigrex).
- Various S-Rank Soldiers: Often found in the later, more challenging Extra Ops or as rewards for high mission ranks.
Recruiting these legendary soldiers can provide a massive boost to your Mother Base's capabilities, especially in R&D or Combat. Keep an eye on mission briefings and online guides for specific locations and recruitment methods. Some require specific weapons (like the Love Box) or actions to trigger their appearance. These recruits are often the key to unlocking the most powerful weapons and items in the game.
