Speaking at an event organised by women officers of the Armed Forces Medical Services (AFMS) in New Delhi, Ms Sitharaman called upon them to grab every opportunity coming their way saying "blanket rejection" of males or females should be completely avoided.
"I think there should be more women in the armed forces," she said.
Women achievers in India have a very different environment, she said, pointing out that a number of women have achieved great heights in their area of specialisation but such examples were not sustained.
Three distinguished veterans of the AFMS, including the first woman Air Marshal, Padmavathy Bandopadhyay, Vice Admiral Punita Arora and Lt Colonel Farida Rehman were felicitated by the minister at the event organised to celebrate the International Women's Day.
She asserted that there was no gender discrimination in the IAF and termed it the best place for women to work at.
Lt General Bipin Puri, Director General of AFMS, said women officers and staff were its "extremely important assets".
