Night Infiltration Game 
This Game is meant for Boy Scouts.
Decide for yourself if it is appropriate for your younger scouts or not.
Preparation:
Define the play area about the size of a football field, but with some vegetation for cover.
Instructions:
2 adults are the 'sentries' roaming back and forth across the middle of the play area with flashlights. Their job is to stop infiltrators from both teams.
Divide the troop into two teams. One team must wear a white kerchief or some other easily identifiable item so the sentries can tell which team they are on.
Each team goes to opposite ends of the field.
On 'GO' signal, scouts try to infiltrate their way past the sentries to the far goal line in a pre-set length of time.
If a sentry shines his light on a scout, that scout must return to his starting line.
At the end of game time, teams receive 1 point for each scout that made it to the far goal.
