Choosing between IMA (Indian Military Academy) and OTA (Officers Training Academy) is one of the most important decisions for CDS aspirants. Both academies train future officers of the Indian Army, yet they differ significantly in entry type, training structure, service tenure, and career prospects.
At The Lakshya Academy, we guide defence aspirants to make informed career decisions, not emotional ones. This blog will help you clearly understand the difference between IMA and OTA so you can choose the path best suited for you.
