There are many different ways to find pen pals in the military. Several organizations and websites offer to connect people with members of the military both in the field and at home for correspondence. If you want to form a pen pal connection with a soldier that may lead to romance, you must visit more specialized sites.
Visit the website Military Friends and create a profile. This is a free service and can connect you with members of any branch of the United States military, deployed or otherwise. The site allows chat, email and access to advice columns and other information with the creation of your free profile.
Join the website Military Singles Connection. The site is free and you can create your profile, add your photo and begin browsing and communicating through the site's messaging system immediately.
For a less traditional path to the same goal, check out the message boards on AOL. There is a military pen pals service for those 18 years and older where members of the armed forces and civilians can mingle and communicate. You will have to create an AOL screen name to join in the conversation.
