Actually this one can be useful as adviser to paper generals as he has actual war experience ,seeing active service in the Civil War with elite infantry, took part in major offensives and played a major role in the defeat of the Tamil Tigers .
He is also a living proof that military officers are not suitable to run business or lead the country's economic development.-I hope he does not take umbrage as its only my personal opinion .
On the other hand can a medical doctor be a good defense minister?- I hope he does not find it raucous, rambunctious,and discombobulating.
