Any recruit found wearing the mask improperly is dead. Division 109 suffers casualties before a shot has been fired. Recruits shoulder rifles and the scenario continues. But when the hatch is thrown open he jerks back as if he had walked into a brick wall. Dense white smoke pours out of the space.
Visibility is zero.
The recruit slowly shuffles in, and the two teams follow. The smoke, lack of sleep, and difficulty communicating are too much. The first try is a failure. Expecting this, the facilitators bring them out to talk about it, then send them back in. We were faster, a lot more energetic.
