S-Rank Needed?

[DCello]

Is S-Rank needed to unlock all the side missions or I only need to finish Ground Zeroes and collect all 9 XOF patches?

In fact, does S-Rank unlock ANYTHING or it's just a completionist/afficionado thing?

You need S ranks for 100%

I completed Ground Zeroes last night with a B rank and unlocked some guns. When I played a Side Ops, I didn't had those guns unlocked in the starting area.

Earlier today, I completed a Side Ops with an S-Rank. However, the sniper gun I unlocked wasn't avaiable on the Ground Zeroes mission starting rank, either.

I'm a bit lost ._.

it is right.

you unlock weapons for the mission you played. not for all.

Short and clear: S-Rank is only for 100% completion. You don't unlock anything other than extra weapons at the start of the mission for getting an S-Rank.
Although it's still unclear if you will get something in TPP for 100% completion or not.

S Ranks don't give you anything except achievements and the 100% rating if you're a completionist.

Everything else is independant from rankings, so you don't have to master the game to find all of the unlockables or easter eggs.

I think some weapon unlocks might be S ranking though, but I don't know if those will really be important other than having a new toy to mess around with in Ground Zeroes on those specific missions you mastered.
