Following the events of "Prologue":
"Who's your best man?" Price asked Nikolai.
"Yuri," Nikolai said without hesitation. "Ex-Spetsnaz. Only man I know who hates Makarov more than you."
"Get him," Price ordered. "They'll use the ridgeline for cover and fly in from the south."
"How do you know?" Nikolai asked.
"It's what I'd do."
A few minutes later, Yuri entered the room and stepped forward.
Price sized him up in a second. He's battle-hardened and sure of his skills. Although the Russian was not breaking eye contact, Price noticed that Yuri was gripping his rifle tightly. And nervous… But not about the coming battle.
Yuri glanced at Soap as the wounded soldier groaned in pain.
Price turned away. Can't question the help now. That'll come later. We've got to get Soap to safety.
There was an explosion in the distance.
"How the hell did Makarov find us?" Price asked Nikolai.
"I don't know," Nikolai admitted, grabbing a weapon. "I stole Shadow Company helicopter when Shepherd blew base. Makarov shouldn't have been able to track it."
"Did Makarov give you anything?" Yuri asked in English. "Any help? Any tech?"
"He…" Price froze. "Son of a bitch."
Price pulled out the small device he had activated in order to intercept Shadow Company's communications.
"The decryption codes," Nikolai spat.
"He must have back-traced the activation codes to find our location," Price said quietly. He threw the device on the floor and smashed it with his foot, frustrated at his own ignorance. The enemy of my enemy.
Yuri moved to the window. "We don't have much time."
Price looked at Yuri suspiciously. "How did you know?"
"Makarov doesn't seem like the kind of man to give anything for free," Yuri answered.
Price opened his mouth to pursue the subject further but stopped as a nearby house exploded.
Nikolai looked at Price. "They're here."
