could the detour be something like "trenches or front-lines"?
we see one team (JJ i believe), walking in what looks to be a trench
and we see several other teams going through an obstacle course of sorts while under "heavy fire"
maybe the trenches are a maze thing where teams have to figure out how to make it to the end, or at least find something in there?
and then the battlefield is an obstacle course where if teams get "hit" (with paint perhaps?) they must start over?
we do hear Jordan (male) say he was "hit".
