Do I get an S rank based on in-mission strategy e.g. not getting spotted, no kill bonus ect…
or is it for finishing all parts of the mission including the main parts?
Example in the mission you need to save Kaz, theres capturing the truck driver, not being spotted by the skulls ect…
Staff Morale effects your soldiers abilities. When they are in good morale, they will perform better than their skills, indicated by a yellow boost to their bars:
The primary factor for Morale is GMP balance. Keeping a surplus is the best way to ensure that Morale is not negatively effected. You can also visit the soldiers individually at Mother Base to raise their morale.
Customizing weapons is not very hard, you just need to know where to look.
First things first: You need to have completed a mission where you
Extract a Legendary Gunsmith
It's a Side Op, and is labeled as above. He'll become a part of your staff and you'll be able to customize weapons.
You're now done with the above, so how do you go about the actual "customization"?
First you need to be in the ACC (Aerial Command Center), you get there by just calling your chopper for a transport.
Next, you open your iDroid and go to the Mother Base tab and choose Customize.
And there you go, you should now have several options for customization.

There are 2 ways to get an S Rank.
The first is to get 130,000+ points on the mission summary screen. Performing certain mission tasks, rescuing prisoners, and receiving bonuses (such as No Reflex) all give you points. Finishing quickly gives a rather large amount.
The second way is much harder; there is a "no trace" bonus that is earned when Snake leaves no sign he was there. This means no shots fired (would leave shell casings), no thrown magazines (or any other items), and never being seen. (You can fulton things, but that's about it).
But, I had no trouble getting an S Rank on every mission the "regular way". Shoot for the time bonuses -- they are really powerful. "Perfect Stealth, No Kills" is also worth a lot of points.
