Which of the Mother Base platforms to expand first
Before we begin, it’s important to note that certain items require some platforms to be of a certain level in order to be crafted. This is sometimes set arbitrarily and may take into account more than the R&D level. As such, it’s always best to shoot for an item or piece of equipment and plan that way.
Out side of these, your priority should be expanding the the R&D platform as soon as you have access to it. Simply select the Mother Base tab and select Base Facilities. This platform is crucial in upgrading your tools (which start out performing poorly) as well as developing entirely new ones. Almost all gear upgrades or research requires you to have reached a certain level for the platform, so make sure you devote your early resources to expanding the staff limit.
A cheaper way to increase the number of staff members on all platforms without expanding each one is the Command platform. Expanding it gets you space increases across the board. They’re small however compared to what you’d get for expanding each one individually, naturally.
Then on to the Base Development platform, which processes the materials you gather in the field. Expanding it means faster material processing and even more material gain from your field ops.
Support and Intel platforms come later. The first provides you with a wide range of ways to help you out in the field. These can be lethal (like bombardment), or non-lethal like smoking a location. Later on, it can go as far as manipulating the weather to create certain conditions.
The Intel platform is responsible for making it easier for you to see enemies by pre-marking them or noting them on the map. This goes for plants and other objects of interest as well. Expanding it means more accurate and frequent reports.
Finally, the Medical and Combat platforms should be tended to as needed. The Combat platform is responsible for sending out teams on missions. This is similar to the Brotherhood stuff from the Assassin’s Creed games where they get you resources by fighting certain battles. You can only have two active at a time, unless you expand into a FOB.
The Medical team is situational. If you send out units to combat regularly, they will need someone to heal them when they get back. Increasing its level makes this process faster. One thing to note is that it makes extracting injured recruits from the field more successful. This is one of those nice-to-haves, but far from crucial, since you can just carry people to the chopper.
You should also keep in mind that fuel is the most required of resources. Almost all expansion projects require it and it can be somewhat hard to find, so make sure you have it stocked as high as you can above all else.
