OCS meaning in Community ?

An officer candidate school (OCS) is a military school which trains civilians and enlisted personnel in order for them to gain a commission as officers in the armed forces of a country. How OCS is run differs between countries and services. Typically, officer candidates have already attained post-secondary education, and sometimes a Bachelor's degree, and undergo a short duration of training (not more than a year) which focuses primarily on military skills and leadership. This is in contrast with a military academy which includes academic instruction leading to a bachelor's degree.
