Dear Prakash,
You are serving in the Indian Army and about the Corporate, it's entirely different. There, you have only three branches to work, and here, there are a lot of segments, and everything has to be handled by one person. Don't think that corporate is a pink; it's like a war front.
With regard to your CV, just put the contents about your working profile and your MBA. Do not make it lengthy. Just put the duties you perform in a single-word manner. As I do not know what your cadre is in the IA, I cannot give any comments on the same.
Take care, God bless u
