Complete each of the following 10 Side Ops missions in order to obtain the corresponding Memento Photos.
Each mission involves locating, knocking out, and extracting a soldier. Stealth is a key component, so use cover and the cardboard box. You can use D-Dog to help locate soldiers, and using the iDroid to play "Love Deterrence" will distract them. A sniper rifle with tranquilizer darts will also come in handy. Missing means having to find the soldier all over again.
Once you have all 10 Memento Photos, give them to Paz. You'll also need to build the first part of the Medical Platform before you can visit her. Then leave her room to find the Morpho Butterfly on the wall. You'll also get Emblem Parts.
