At nine o'clock at night, at a makeshift airport on the outskirts of Fallujah.
To prepare for tonight's hoisting, Yousuf had made full preparations by arranging a generator and some outdoor lighting equipment to be brought here during the day.
The team responsible for the hoisting and transportation consisted of three container trucks and a crane truck dispatched from the "Musician" defense transportation fleet.
The SA-9 anti-aircraft missile launching system had a total weight of just about 8 tons, which was not hard to load.
Song Heping stood in silence not far away, watching as the driver loaded the last launcher vehicle into the container, then lifted his hand to check his watch and took a glance around.
He could almost be certain that in the surrounding darkness, someone was watching him with video equipment and high-powered surveillance gear, probably clear enough to see the sweat on his face.
"Song, everything is loaded."
