Another fun game is, well I have no idea what its called but I'll just call it flashlight for the moment. Basically you have 1 guy with a flashlight and a whistle, and the rest of your section cammed up. its easier to play in the dark, but more challenging in the day (obviously no flashlight is required here).
This game can be played in a field, but is best suited to a woody area.
The person that has the flashlight and the whistle sends the rest of the section off in any direction with a minimum of say 50ft and gives them a couple mins to cam up and hide. Then the person with the whistle blows it once to start the game. Basically the idea of the game is to get to the person with the flashlight without being seen. We played it so the person with the whistle would give you 30 seconds and then blow the whistle then give you 3 seconds to hide, then turn the flashlight on for 10 seconds and so on.
Not sure if this applies to night games? I learnt this one in scouts, we didn't really play games in cadets.
