Most commentators are assuming a computer-based game which is a reasonable assumption, but not guaranteed. They might actually want to do something different and get out into the woods.
My experience with CTF games using paintball guns is the the vast majority of players want to strike out on their own or with a couple friends and be the hero. No concept of discipline, organization, or coordinated action exists. These groups of Rambos are easy pickings for any group that has learned to work together in a planned action. Military veterans and most people who have spent time playing in team sports will have developed the skills and ability to work in a group. Enlist people like that to teach your students to work together.
