Why Choose a Specific Corps?

Each corps offers unique training durations ranging from 6 months to 2 years and diverse postings, from border regions to urban centers. For instance, those interested in aviation may prefer the Army Aviation Corps, while medical professionals might choose the Army Medical Corps. Recruitment data suggests a high demand for technical corps due to modernization efforts.
