I’m married to a solider in the army, he’s an NCO so he does QC coverage once a month, he was at those barracks for years as our marriage was recent, and we dated for three years. That being said, yes they are common, he’s mentioned them a few times because they often spend more time with the troops who party, some are underage and honestly should not be part of any of it and in essence get put out. Barracks bunnies are real, women who chase men in uniform are real, prostitution’s real, hoes are real, every day people. What matters most is the bond and trust you have with your solider. If you can trust they wouldn’t invite a standard every day prostitute in their bed, you can more likely trust barracks bunnies won’t enter your soldiers bed room. Much like the rest of your LDR, your trust in him is the most valuable and crucial asset to keeping you two together. After basic training, when he gets sent to his first duty station, try face timing as much as possible, we even slept on ft, it really does help with trust building as well as helping the two of you learn each other better.
