It's cold, dark, and you're hungry with nowhere to go.

As you stumble blindly in the snowy forest of who knows where, you see a flashlight in the distance and the voice of a male, who was quietly singing.. but in a foreign language, the language of your country's enemy.

Suddenly you sneeze. The man goes quiet as he approaches where you happen to be.

You make out the faint outline of an assault rifle in his hand. He was indeed an enemy soldier. And you were in the enemy's territory, trespassing.
