Previously, the Spanish Army had a large number of lower-ranking officers who had never received proper military education, which also affected the combat effectiveness of the Spanish Army.
There are many factors that impact a military's combat effectiveness, but one of the important factors that can practically determine the fighting capability is the military literacy of these lower-ranking officers.
No matter how outstanding the general leading the army is, if the lower-ranking officers lack sufficient military literacy, the general's orders are unlikely to be fully executed.
If these lower-ranking officers possess excellent military literacy, even if the commander as a leader is not highly capable, at least the army can remain relatively stable.
