It was a scenario tuhon threw in unexpectedly to see what kind of reaction would result. Initially it was 2(closed) vs 1fdr(open), but 2 more fdrs(open) were thrown in the middle. The 2 that were stacked ended up breaking off. The lead in the stack addressed the original fdr while the rear stack took on the 2 new fdrs. It was more of a thought process experiment. We discussed different things about it & what we could have done or tried afterwards.
Made me think about being in a dark environment against an attacker who has nightvision on.
