You could try an "Attack" and "Defend" scenario with laser tag guns(If you have the money) if no laser tag guns..use flashlights
And make sure its dark out...
If its light out...
Ask your CO first,and see if its ok with the cadets participating...If you can use paintballs...not paintball guns just paintballs...then the cadets can throw them at eachother
Or if its a winter weekend--->Snowballs!
