The decision to accept or reject a potential recruit into the military involves various factors, and it is ultimately up to the specific policies and regulations of the armed forces.
Even though your domestic violence charge was dismissed, the military may still take it into consideration during the recruitment process. They often conduct thorough background checks to ensure they are enlisting individuals who meet their standards of character, discipline, and conduct.
A history of domestic violence, even if the charge was dismissed, might raise concerns for the military regarding the applicant's ability to maintain good order and discipline within the ranks. Each branch of the military has its own specific guidelines and policies, and some may have a zero-tolerance policy when it comes to certain criminal histories, including domestic violence-related incidents.
Keep in mind that the military has the right to make recruitment decisions based on their criteria, and sometimes, they may choose not to accept an applicant with certain legal or behavioral histories, even if it doesn't require a waiver.
If you have concerns or questions about your specific situation, it's best to directly contact the recruitment office of the military branch you are interested in joining. They can provide you with accurate and up-to-date information regarding their enlistment policies and help you understand the decision made in your case.
