While Brian Horn was serving in Iraq, his parents sent him an average of six care packages a week. When he called home to ask for more, they thought he was kidding. He wasn’t—he wanted to give care packages to soldiers who received little or no mail. So Brian’s parents started the Any Soldier website, which has served more than two million troops. Troops serving overseas request items that their units could use, from underwear and socks to baseballs and puzzles. You choose a request to fill, and when your package arrives, the person who made the request gives your letters or care package to people in the unit who don’t get much or any mail. Keep in mind that this isn’t as simple as bringing a care package to the post office. You’ll need to download and fill out customs forms, and they’ll list shipping limitations that you’ll want to know about before buying care package items.
