out strategizing the enemy

How do you measure things that are impossible to measure?

There was an enemy that wanted to kill us. There was 1 boy that they were after. We were trying to use 2 others as decoys to draw their fire. In the middle of the night. We weren't as successful as we thought we would be. It was a lot of work to try to draw their fire. Scraping at the door. Slamming the door. Would they wake up?
