Season 7 week 4 and this second solo challenge is a mission, but this one could be mildly troublesome.
In Extreme difficulty, without being visually detected and using only CQC, deploy to Espiritu Santo Alpha then complete the mission ‘La Santera’.
Sounds straightforward, but enemies are highly vigilant in extreme difficulty, and we have to get close enough to use CQC unless we cheat and use sync shots (you can use those without failing). This is a base with roaming patrols, snipers and a lot of SB enemies, so remaining unseen could be tricky.
This base also has two drone jammers, which are a pain, so scoping the area beforehand is a bit more difficult as well. I actually quite like my approach for this one, but did you find another way? Let me know in the comments.
