Yeah definitely. I'm sure they explained the scenario/challenge before
I don't think they did lmao. The website has 0 information around that and even the VOD somebody else posted here has no info on it in the first 10 minutes, at which the announcer says "I will of course repeat what is necessary to do in the course over the different attempts" or some such. Maybe they reveal the scenario at hour 7.
I don't think any of it makes sense as a "real world" challenge unless you approach this with SWAT team member cop brain. I'm not gonna claim a police sniper rushing up 4 flights of stairs to hit an impressive shot right after, out of breath, isn't tense or exciting or whatever, but it is SWAT Team Member Daydream. For an actual police force, at the point where that is necessary to happen you fucked up. Either on the strategical level for the situation or like layers and layers above on a like "this is a government entity with a mission statement"-level.
This challenge and the entire competition tells you nothing about policework other than how the competing teams would fare if they were thrown into action movie situations. It's impressive displays of skill and athleticism - I mean I don't think I run half that fast as the chinese dummy cops without sharing a bodyweight dummy with somebody - but at it's core it's police porn, not police work.
