Civilians can sign up to be pen pals with soldiers through organizations such as Soldier Penpals and Adopt A U.S. Soldier. Volunteer pen pals can have ongoing correspondence with an individual soldier during deployment, or they can send a one-time letter or package to a group of soldiers.
Some organizations connect pen pals with soldiers to provide encouragement and support, as does Adopt A U.S. Soldier. Other organizations, such as Soldier Penpals, provide a channel of communication to pursue romantic interests with a deployed soldier. These private organizations are for profit and act in a similar fashion to other online dating sites.
