Depends totally on who and where you're sending them. The more austere locations will take anything you send. Candy, wet wipes, toiletries, magazines, and etc. I've deployed to the more built up bases and if it was an enduring location for our mission set there would be a giant closet filled with years worth of toiletries. I've also deployed to bases with nothing but 10 tents and a TOC and the bi-weekly mail delivery was a godsend with whatever bullshit showed up.
