There’s a common misconception that anyone commissioned in the Army is automatically promoted. However, this is far from the truth.
In reality, the Army has one of the most stringent merit-based systems for promotions and progress. Only a certain percentage of all ranks are promoted to the next rank based on their performance, while the majority of personnel retire at junior ranks.
Moreover, all ranks have to pass different courses at various stages of their service for promotion, and their promotions must be supported by their performance on the ground, which is evaluated by their superiors.
Before the promotion, each rank has to prove their mettle in challenging areas, demonstrating their ability and suitability for the higher rank.
