"Two minutes until white phosphorus smoke charging! Everyone, put on your gas masks and connect the oxygen tanks immediately! No time to hesitate!"

"Shit, I can't believe this day has come."

"Close the windows! Don't leave any gaps, make sure no hole is left open where white phosphorus might enter!"

The makeshift fortress, already busy, became even noisier as the sirens they had temporarily set up blared.

The officers moving quickly around the fortress summoned dozens of soldiers, handing them a cylinder and rubber tubing between oxygen tanks and oxygen cans, which had been piled up in a temporary warehouse behind the fortress.

Soldiers receiving their cylinders wore gas masks with tense expressions, while those who didn’t receive one quickly retreated along the wall of the makeshift fortress, following the shuttle bus stop towards the HQ.

It was almost like they had rehearsed this, or as if they had prepared for it—quick and seamless.
