Final answer:
The provided information discusses a military graduate and mentions the General Schedule (GS) pay scale for civil services but does not specify the three automatic promotion ranks for soldiers. Automatic promotion often applies to the initial officer or enlisted ranks and is based on time in service and performance in many military branches.
Step-by-step explanation:
The question relates to automatic promotion ranks within a military context, specifically those in the Army or analogous military branches. In many military services, certain ranks come with automatic promotions based on time in service and performance. However, the information provided does not directly state the automatic promotion ranks in the military. Instead, it highlights a military graduate with a lieutenant's commission and provides some details about the civil service General Schedule (GS) pay scale, where employees are promoted through various grades based on education, experience, and performance.
For a military graduate, such as the individual referenced with a lieutenant's commission, automatic promotions might occur at the initial officer ranks, depending on the specific policies of the branch of service. Typically, in many armed forces, officers may be promoted from second lieutenant to first lieutenant and then to captain based on time served and performance in their roles. Automatic promotions for enlisted personnel might include ranks that vary by country and service branch. Conversely, the GS pay scale pertains to civilian federal employees, where automatic step increases within a grade occur based on time and performance.
