What article under the UCMJ cover public display of affection?

The Uniform Code of Military Justice (UCMJ) does not specifically have an article that addresses public displays of affection (PDA) directly. However, such behavior can potentially fall under Article 134, which covers conduct unbecoming of a service member. This article addresses actions that bring discredit upon the armed forces, which could include inappropriate PDA in certain contexts. Ultimately, the appropriateness of PDA may depend on the circumstances and the military regulations of the specific branch.
