A little snippet from the Nov 2013 JI
Prohibitions/restrictions

Prohibited articles
Here is a list of prohibited articles:
1. Fire arms or edged weapons (switch-blade knives, knives with blades longer than 6 inches)
2. Food stuff (fruits, chips, candy, etc.) and drinks, including supplements
3. Alcoholic beverages
4. Illegal substances (including caffeine concentrate "wake up")
5. Materials with sexual connotation (magazines, photos, DVD, accessories, etc.)
Restricted materials
1. All electronic devices (cellular phones, iPods, iPads, laptops, etc.) are considered restricted materials in the following manner:
• No devices can be used/carried during training hours.
• Cellular phones are allowed on weeknights after training has concluded but no earlier than 6:00pm. Reasonable usage should be restricted to communications with family and friends.
• All other devices MAY be allowed on weekends in garrison if there is no training scheduled and if performance has been
judged adequate by the instructors.
Game consoles are not authorized and will be confiscated and secured upon arrival. Any other devices may be confiscated at any time by platoon staff should there be any abuse or unauthorized use.
2. Personal vehicle: unless you have special permission from the chain of command, you can use your personal vehicle only during the leave weekends that you are allowed to leave the garrison. All other uses are forbidden.
