Why can't the difference between the two third-class merits of the army be less than 6 months?

Because I don't know the specific situation, it's not easy to answer. But I can send you a document for your reference:

According to the Law of the People's Republic of China on Officers in Active Service and the Notice of the General Staff Department, the General Logistics Department and the General Logistics Department on Selecting Grass-roots Cadres from Good Soldiers who Graduated from Colleges and Universities, the army can directly promote cadres from good soldiers who graduated from colleges and universities and enlisted. I. Select the object and scope 1. Selection targets: military personnel who have participated in the national unified entrance examination for ordinary colleges and universities, been admitted to ordinary colleges and universities by the provincial (city, autonomous region) admissions office, obtained full-time undergraduate education and bachelor's degree, and performed well after enlisting. 2.
