Yes, but there are conditions: military schools mainly train officers and civilian cadres for the army. Soldiers who apply for military schools must have a high school education or equivalent, have served in active service for more than 3 years, and are under the age of 22 (as of June 1 day of that year). If you are a soldier of ethnic minorities or a college student enlisted in an ordinary university, the age can be relaxed by 1 year.
