“
A Soviet force has holed up in a small town, threatening to kill a hostage every 5 minutes until their demands are met. We do not negotiate with terrorists -- explain this to them. Locate the hostages, free as many of them as you can, and get them safely to a nearby abandoned Church. Once done, return to your drop-off point, signal for reinforcements, and finish off the Soviet forces. - Mission briefing
