Off the top, FOBs should still have guards. I think they provide some good immersion. But since there's no player-on-player fighting, they don't actually serve a function in PvE. FOB raids just aren't a thing.
With that in mind, they shouldn't be lootable.
For those of you that have killed and looted any of them, sorry to suggest taking away this potential gameplay - but there's a TON of ways to acquire gear.
