It's still daylight in your attached photo, and the minimap shows that there's at least one opponent guarding the house near the medkit required to heal your forth squad member. Had you completed that part of the mission, you'd have triggered a cutscene and fast-forwarded into a nighttime setting, ready to infiltrate the base.

This cutscene is important, as it'll not only show you exactly where to cut the fence, but also suggests which soldier to sneak in with, as well as designate the meeting point to park your remaining squad members in the meantime.

Regarding your other questions: the officer who requires healing is lying where you left him at the beginning of the mission, and the agents list is supposed to be in the house the German officer heads towards once you've snuck into the base.

Hope this helps.
